## What does slope represent in a force vs current graph?

Literally the slope means force per unit distance or force gradient. An example is spring constant.

## What is the relationship between the magnetic force and the current through the conductor?

Current is directly proportional to magnetic force for a straight current carrying conductor in a uniform magnetic field. So the force is directly proportional to the size of the current. Practically this means the following: If the current is doubled the force on the conductor will double.

For a wire exposed to a magnetic field,F=IlBsinθ F = IlB sin ⁡ describes the relationship between magnetic force (F), current (I), length of wire (l), magnetic field (B), and angle between field and wire (θ). The direction of the magnetic force can be determined using the right hand rule, as in fig [].

## What is the relationship between the length of a wire and magnetic force?

Taking B to be uniform over a length of wire l and zero elsewhere, the total magnetic force on the wire is then F = (qvdB sin θ)(N), where N is the number of charge carriers in the section of wire of length l.

## What important discovery did physicists Michael Faraday and Joseph Henry make?

What important discovery did physicists Michael Faraday and Joseph Henry make? They discovered that electric current can be produced in a wire simply by moving a magnet in or out of loops, or electromagnetic induction.

## How does the direction of current affects the magnetic force?

The magnetic field produced by an electric current is always oriented perpendicular to the direction of the current flow. Similar to the situation with electric field lines, the greater the number of lines (or the closer they are together) in an area the stronger the magnetic field.

## What is the physical meaning of the vertical intercept of your graph?

In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0.

## How does the length of the conductor affect the magnetic field?

The magnitude of the force on a current carrying conductor increases when the strength of the magnetic held is increased. The magnitude of the magnetic force also depends on the length of the wire in the magnetic field. The longer the wire in the magnetic field, the larger the force on the wire as shown in Figure.

Slope describes the steepness of a line. The slope of any line remains constant along the line. The slope can also tell you information about the direction of the line on the coordinate plane. Slope can be calculated either by looking at the graph of a line or by using the coordinates of any two points on a line.

## What is the physical meaning of slope?

Slope is the change in the y-coordinate with a unit change in x coordinate. ( means y changes by p units for a unit change in x) ( represents change) When the value of y coordinate increases with an increase in x, we say the graph has a positive slope. (

## What is the difference between magnetic field and magnetic force?

Magnetic field is the strength of magnetism created by a magnet, whereas the magnetic force is the force due to two magnetic objects. The concepts of magnetic field and magnetic force are widely used in fields such as classical mechanics, electromagnetic theory, field theory and various other applications.

The Englishman William Gilbert (1540-1603) was the first to investigate the phenomenon of magnetism systematically using scientific methods. He also discovered that the Earth is itself a weak magnet.

## What is the meaning of slope in economics?

The concept of slope is important in economics because it is used to measure the rate at which changes are taking place. Slope measures the rate of change in the dependent variable as the independent variable changes. The greater the slope the steeper the line.

## What does slope value mean?

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. A slope with a greater absolute value indicates a steeper line. The direction of a line is either increasing, decreasing, horizontal or vertical.

In mathematics, slope is usually defined as ‘rise over run’ – or the ratio between the change in the y-variable and the change in the x-variable ( ).

## How is the direction of magnetic force determined?

The right hand rule states that: to determine the direction of the magnetic force on a positive moving charge, ƒ, point the thumb of the right hand in the direction of v, the fingers in the direction of B, and a perpendicular to the palm points in the direction of F.

## In which direction does the magnetic field exert a force on the electron at its initial position?

For the electron, the magnetic field will exert a force directed into the plane of the paper (or if travelling on the earth, this will be towards the earth). For the proton, the magnetic field will exert a force out of the paper (or if travelling on the earth, this will be away from the earth).

## How do you describe and determine the direction of a magnetic field produced by an electric current?

Key Points Another version of the right hand rules can be used to determine the magnetic field direction from a current—point the thumb in the direction of the current, and the fingers curl in the direction of the magnetic field loops created by it.

The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x. The y-intercept indicates the y-value when the x-value is 0.

## What is the difference between magnetic north and true north?

True north is a fixed point on the globe. Magnetic north is the direction that a compass needle points to as it aligns with the Earth’s magnetic field. What is interesting is that the magnetic North Pole shifts and changes over time in response to changes in the Earth’s magnetic core. It is not a fixed point.

## What is magnetic force ks2?

An explanation of how magnets work by using their poles to either attract or repel objects. Only metals which contain iron, nickel or cobalt are magnetic. The two poles which are the same will repel each other, and the two poles which are different will attract each other.
