Tardigrade Admin · Accepted Answer

Time varying vecB will induce emf as ε=-(d φ/d t)

Q. An emf can be induced in stationary coil if it is kept in

Stationary uniform magnetic field

Stationary nonuniform magnetic field

Time varying magnetic field

Not possible

Time varying $B$ will induce emf as
$ε = - \frac{d ϕ}{d t}$
