If a magnetic field is applied to a liquid in one arm of a narrow $U$-tube, the liquid level in that arm is lowered. The liquid in U-tube arm is
1 non-magnetic
2 paramagnetic
3 diamagnetic
4 ferro-magnetic
Explanation:
C In a magnetic field's applied to a liquid in one arm of a narrow. U-tube the liquid level in that arm is lowered then the liquid in the U-tube arm is diamagnetic.

If a magnet is dropped through a vertical hollow copper tube, then
1 the time taken to reach the ground is longer than the time taken, if the tube was made out of plastic
2 the magnet will get attracted and stick to the copper tube
3 the time taken to reach the ground is longer than the time taken, if the tube was made out of stainless steel
4 the time taken to reach the ground does not depend on the radius of the copper tube
5 the magnet will be repelled away by the tube
Explanation:
A When the tube is made of copper's then a emf is induced in the tube when the magnet is droped in tube. This emf pushes magnet upward but in case of plastic tube no emf will be induced. So, the magnet drop without any upward force. So, time taken in copper tube $>$ the time taken in plastic tube.

A deflection magnetometer works on
1 Coulomb's law
2 Tangent law
3 Curie law
4 The law of vibration of a magnet
Explanation:
B A deflection magneto meter works on the tangent law. These fields are earths magnetic field in N$\mathrm{S}$ direction and field magnet in $\mathrm{E}-\mathrm{W}$ direction and the two magnetic field are perpendicular to each other.

The effect due to uniform magnetic field on a freely suspended magnetic needles is as follows
1 both torque and net force are present
2 torque is present but no net force
3 both torque and net force are absent
4 net force is present but not torque
Explanation:
B When the magnetic needles are suspends freely in uniform magnetic field the equal and opposite forces act on the polls of needle, that given rise to a torque. But net force will be zero due to action in opposite direction.
