An electromagnet is a type of magnet in which the magnetic field is produced by electric current. The magnetic field disappears when the current is turned ... more
When current is passed through the loops, the magnetic field exerts torque on the loops, which rotates a shaft. Electrical energy is converted to ... more
In magnetostatics, the force of attraction or repulsion between two current-carrying wires is often called Ampère’s force law. The ... more
The magnetic field generated by the electric current, around a straight wire, is related to the electric current and the distance “r” from the ... more

The magnetic field in the volume of a long, thin loop of wire, wrapped around a metallic core (solenoid) when an electric current is passed through it, ... more
Generated at the center of a circular wire by the electric current, related to the electric current and the distance from the wire to center of the circle.
