A circular coil of 20 hours and radius 10cm is placed in an uniform magnetic field of `0.17` normal to the plane of the coil if the current in the coil is `5.0A`. What is the
total force on the coil.

Text Solution

Verified by Experts

Number of turns, `N = 20`
Radius of circular coil , ` r = 10 cm = 0.1 m`
Magnetic field , `B = 0.1 ` T
Angle between area vector and magnetic field, `theta = 0^(@)`
Current , `I = 5.0 A " " (A = pi r^(2) = "Area")`
The forces on the planar loop are in pairs
`i.e., F_(1) = - F_(2) " and " F_(3) = - F_(4) `
` :' ` they are equal and opposite to each other , the total force on the coil is zero .
