Expert Solution & Answer

To determine

To Draw: Magnetic field due to a bar magnet.

The direction of current inside the circuit and the direction of force.

Explanation of Solution

Introduction:

Direction of magnetic field is from north pole to south pole outside the magnet. There is no magnetic field inside the bar magnet.

After closing the circuit, the current will flow from right to left. i.e. current will flow clockwise. This is because, the current induced in the circuit always opposes the change.

Direction of force can be calculated by using Fleming’s right-hand rule.

By this rule, three fingers of right hand are stretched such that thumb, first finger, middle finger are at 90 degrees to each other. If the first finger points along the direction of magnetic field, the middle finger points in the direction of the current, then the thumb will give the direction of force.

Applying this rule in the given condition, direction of force will be outside the paper.

Conclusion:

Direction of current is from right to left hand. The direction of force is out of the paper.
