Question

define flux . how does a movimg magazine generate electric current. explain with diagram​

Answer 1

When a coil of wire is moved through a magnetic field a voltage is generated which depends on the magnetic flux through the area of the coil. ... Electric motors and generators apply Faraday's law to coils which rotate in a magnetic field as depicted in Figure 3. In this example the flux changes as the coil rotates

If a coil of wire is placed in a changing magnetic field, a current will be induced in the wire. This current flows because something is producing an electric field that forces the charges around the wire. (It cannot be the magnetic force since the charges are not initially moving).
