A 52.5-turn circular coil of radius 4.90 cm can be oriented in any direction in a uniform magnetic field having a magnitude of 0.465 T. If the coil carries a current of 26.3 mA, find the magnitude of the maximum possible torque exerted on the coil.

Explanation:

Given :

No. of turns

Radius of circular coil m

Magnetic field T

Current A

For maximum torque,

 τ =

Where area of coil =

For maximum possible torque ,

    τ =

    τ = N

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

snell's law

refractve index = sin incidence / sin refraction
