Question

The right edge of the circuit (Figure 1) extends into a Part A B=48mT uniform magnetic field. What is the magnitude of the net force on the circuit? Express your answer with the appropriate units. Part B What is the direction of the net force on the circuit?

Answer 1

The magnitude of the net force on the circuit cannot be determined without the length of the wire. The direction of the net force depends on the direction of the current in the wire.

Step-by-step explanation:

The magnitude of the net force on the circuit can be found using the formula F = BIL, where F is the force, B is the magnetic field strength, I is the current, and L is the length of the wire. In this case, the wire is the right edge of the circuit, which extends into a uniform magnetic field B. To find the direction of the net force on the circuit, you can use the right hand rule. Point the thumb of your right hand in the direction of the current and curl your fingers. The direction in which your fingers curl represents the direction of the force.

For Part A of the question, since the magnitude of the magnetic field strength B is given as 48mT and the length of the wire L is not provided, we cannot calculate the magnitude of the net force.

For Part B of the question, the direction of the net force on the circuit will depend on the direction of the current in the wire. You can use the right hand rule as described earlier to determine the direction of the force.

Answer 2

The magnitude of the net force on the circuit depends on the current, the length of the wire, and the magnetic field. The direction of the net force can be determined using the right hand rule.

Step-by-step explanation:

The magnitude of the net force on the circuit can be determined using the equation F = I * B * d, where F is the force, I is the current, B is the magnetic field, and d is the length of the wire in the magnetic field. In this case, the current and length of the wire are not given, so we cannot calculate the exact magnitude of the net force. However, we know that the net force on the circuit will be zero if the circuit is stationary and the magnetic field and current are perpendicular to each other.

The direction of the net force on the circuit can be determined using the right hand rule. If the current flows in the direction of the thumb and the magnetic field points in the direction of the fingers, then the net force will be in the direction perpendicular to both the current and the magnetic field.
