In radial magnetic field, the plane of the coil of M.C.G. for any position is always

A

perpendicular to the lines of force

B

parallel to the lines of force

C

inclined with `45^@` with lines of force

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B
In radial magnetic field , plane of the coil is always parallel to magnetic induction.
`therefore theta=0`
Thus , `tau_n= n IAB cos theta= n IAB cos 0`
= n IAB (maximum).

Calculate the torque on a 200 turns rectangular coil of length 20cm and breadth 10cm carrying a current of 10A , when placed in a magnetic field. The plane of the coil is making an angle of 60^@ with a magnetic field of 4T .

A rectangular coil of area 5.0xx10^(-4) m^2 and 60 turns is pivoted about one of its vertical sides. The coil is in a radial horizontal field of 90 G (radial here means the field liners are in the plane of the coil for any rotation). What is the torsional constant of the hair spring connected to the coil if a current of 2.0 mA produces an angular deflection of 18^@ ?

A coil is suspended in a uniform magnetic field, with the plane of the coil parallel to the magnetic lines of force. When a current is passed through the coil it starts oscillating, It is very difficult to stop. But if an aluminium plate is placed near to the coil, it stops. This is due to :
