Verified by Toppr

Force on a charge (q) moving in a magnetic field B with velocity v making an angle θ (with the direction of magnetic field (B )is given by

Fm=qvBsinθ

When θ=90o⇒sinθ=1, so  

Fm=qvB

or B=qvFm

If v=1 m/s,B=qFm newton/coulomb.

SI unit of magnetic field is tesla.

Thus, 1 tesla is the magnetic field in which a charge particle moving with velocity 1 m/s perpendicular to velocity experiences a force of 1 newton/coulomb.
