Answer 1

a very strong magnet that uses electric pulses to lift magentic things :)

Answer 2

An electromagnet is a type of magnet where the magnetic field is produced by the flow of electric current. It consists of a coil of wire wrapped around a core of magnetic material. When current flows through the wire, a magnetic field is created, and the strength of the magnetic field can be controlled by adjusting the amount of current flowing through the wire. This property makes electromagnets versatile and widely used in various applications, such as in motors, generators, and MRI machines.
