Asingle-turn current loop, carrying a current of 4.03 a, is in the shape of a right triangle with sides 68.1, 151, and 166 cm. the loop is in a uniform magnetic field of magnitude 99.3 mt whose direction is parallel to the current in the 166 cm side of the loop. what is the magnitude of the magnetic force on
(a) the 166 cm side,
(b) the 68.1 cm side, and
(c) the 151 cm side?
(d) what is the magnitude of the net force on the loop?

Part a)

Part b)

Part c)

Part d)

Net force on a closed loop in uniform magnetic field is always ZERO

Explanation:

As we know that force on a current carrying wire is given as

now we have

Part a)

current in side 166 cm and magnetic field is parallel

so we have

here we know that L and B is parallel to each other so

Part b)

For 68.1 cm length wire we have

here we know that

so we have

Part c)

For 151 cm length wire we have

here we know that

so we have

Part d)

Net force on a closed loop in uniform magnetic field is always ZERO
