WebAnd for magnetic fields we will require a magnet. So let's bring in a magnet, place it close to this coil and see what happens. And we see nothing. There is no glow in the bulb. That means there is no current, but there is a magnetic field because I have kept a bar magnet close to it. This means a magnetic field does not create an electric current. WebWhere, τ is the torque acting on the dipole; m is the magnetic moment; B is the external magnetic field; Read More: Torque Magnetic Moment Unit: In the definition for the current loop, the Magnetic moment is the product …
