A special type of cannon that fires humans out of it, has a mass of 500 kg cannon and is at rest on a horizontal, frictionless surface on a clear and sunny day. When a crazy cool 100 kg clown decided to show how the cannon works they decided to get fired horizontally from the barrel of the cannon and the cannon recoils with a speed of 5 m/s. A very inquisitive Physics student figured out how fast the clown was traveling when leaving the cannon. What value did they come up with?

When a current passes by the electromagnet, a magnetic field is designed in the coil. Changing the magnetic field the current makes the loop in an electrical device to sustain revolving. The generation of an electric current by passing a loop of wire by a magnetic field or moving a magnet by a wire loop.

This electric motor, an electric current causes the coil to rotate, changing and to produce a magnetic field. When the coil is moved then the magnetic lines changes and produce a magnetic field. So the changing of magnetic lines causes the current to flow.
