What is the work done by a magnetic field on a moving charge?
Asked by Topperlearning User | 19 May, 2015, 10:16: AM
Expert Answer

Force on the moving charge in magnetic field is

F= qvBsinθ

Work done per sec on moving charge in the magnetic field

W  = begin mathsize 11px style straight F with rightwards arrow on top times straight V with rightwards arrow on top end style = Fv cosθ

Since Syntax error from line 1 column 56 to line 1 column 97. Unexpected 'mathvariant'. is perpendicular to begin mathsize 11px style straight v with rightwards arrow on top end style, therefore θ = 90°

 W=0

So the work done on the moving charge in a magnetic field is zero.
