Question

Question 2 3 pts Lorentz Force Changing the current through the wire would have changed the magnetic force on the wire. True False Question 3 3 pts Lorentz Force If the balance reads a value lower than the true mass of the magnet, the force on the loop is No answer text provided. downward upward zero Question 4 3 pts Lorentz Force Changing the current through the wire would have changed normal force on the magnet. True False

Answer 1

2. True

Magnetic force is given as,

F = ILBSin(theta)

3. Upward

F = W- mg

4. True

There is no any lateral forces in magnetic all the forces are normal and they changes with the current.

5. FALSE

mass has no relation with current.

6. Force on the loop

As this is the condition for the objects comes under the vicinity of the magnetic field.

7. Decreases

As magnetic field is gievn as,

B = UoNI

8. Length of the wire.

9.

B = F/A× L = (0.000456552) T

10. Strength of the magnetic field

Size of the loop

Because

F = IBL sin theta

11. Magnetic field.

12. Positive

Because it measures the distance of the the approaching wire so it can't be negative.
