On the diagram, indicate the direction of the current through the wire when the circuit is complete.

Predict the direction of the force exerted on the wire by the magnet when the circuit is complete. Explain.

Check your prediction (Do not leave the battery connected for more than a few seconds. The battery and wires will become hot if the circuit is complete for too long.)

Expert Solution & Answer
Check Mark
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.

Displayed below are six statements about electric and magnetic fields and forces, three of which are true and three of which are false. Check the three boxes beside the three statements that are true. OA. The electric force acting on a stationary point charge due to a second charge depends on the velocity of the second charge. B. Gauss's law is true for charged particles traveling at speeds close to the speed of light. C. IF the charge distribution in a region of space is known, then the electric field can be calculated. OD. The magnetic field produced by a small curent loop falls off as 12 at large distances from the loop. O E. When a magnetic field is applied perpendicular to a strip of semiconducting material that is carying a current, positive and negative charge carriers are deflected towards the same side of the strip.
