Ampere and Forces between Two Parallel Currents, Torque
on Current Loop & Magnetic Dipole, Moving Coil
Galvanometer - Level 1(part 2)
1)
Pick out the expression for magnetic field inside a toroid from the following.
2)
A solenoid of 0.5 m length with 100 turns carries a current of 5 A. A coil of 20
turns and of radius 0.02m carries a current of 0.6 A. What is the torque
required to hold the coil with its axis at right angle to that of solenoid in the
middle point of it?
, 3)
Two concentric coils of 20 turns each are situated in the same plane. Their
radii are 60 cm and 80 cm and they carry currents 0.4 A and 0.5 A
respectively in opposite directions. Calculate the magnetic field at the center.
4)
What is the expression for the force experienced by two parallel current
carrying conductors of unequal length?
