A solenoid with an air core has a magnetic field pointing along its axis in the positive x direction. This solenoid is then filled with a diamagnetic material. What changes will this make to the magnetic field along the axis of the solenoid?
A)
The field will point in the -x direction with a smaller magnitude.
B)
The magnetic field will not change.
C)
The field will point in the same direction with a larger magnitude.
D)
The field will have the same magnitude but will now point in the -x direction.
E)
The field will point in the same direction with a smaller magnitude.
Question 2
A small cylinder made of a diamagnetic material is brought near a bar magnet. One end of the cylinder is brought near the North pole of the magnet and is repelled.
What happens when the other end of the cylinder is brought near the North pole of the magnet? A)
The other end of the cylinder will not be affected by the magnet.
B)
The other end of the cylinder will be attracted less strongly by the magnet.
C)
The other end of the cylinder will be attracted by the magnet.
D)
The other end of the cylinder will be repelled by the magnet.
E)
The other end of the cylinder will be attracted more strongly by the magnet.
