A magnet can induce an electrical current in a conductor by creating a magnetic field that causes electrons to move. This phenomenon, known as electromagnetic induction, is the basis for how devices like generators and Transformers work. The strength of the magnetic field and the motion of the magnet will impact the amount of current generated.
The magnet in a compass is a permanent magnet. It retains its magnetism without the need for an external electrical current.
An electrical method of making a magnet involves passing an electrical current through a coil of wire to create an electromagnetic field. The coil is usually wrapped around a core material such as iron, which enhances the magnetic field strength. This process, known as electromagnetism, allows for the temporary creation of a magnet that can be turned on and off by controlling the electrical current.

In a magnet-powered flashlight, a diode acts as a one-way valve for electrical current. It allows current generated by the magnet passing through a coil to flow in only one direction, ensuring that the flashlight's LED light only illuminates when the magnet moves and generates electricity. This helps to convert the kinetic energy from the movement of the magnet into usable electrical energy for the flashlight.
An electric generator works by using a magnet and a coil of wire to convert mechanical energy into electrical energy. When the coil of wire rotates within the magnetic field created by the magnet, it generates an electric current. This current can then be used to power electrical devices.
An electrical current will flow in a conductor, when a magnet is moved next to a conductor - or when the conductor is moved next to the magnet.
A Electro Magnet, caused in theory by the alignment of the particles in the material duo to the current passing through it.

The electrical current stops flowing.
A magnet cannot stop an electric current, but it can influence the flow of the current. Moving a magnet near a wire carrying an electric current can induce a voltage in the wire, which can affect the behavior of the current.

A strong short-lived magnet created by a looped electrical current is an electromagnet. When an electric current flows through a coil of wire, it induces a magnetic field around the coil, which can attract or repel magnetic materials. Turning off the current will cause the magnetic field to cease.
Magnets are related to electrical currents; the electrical current produces a symmetrical magnetic field, i.e., it has a north and a south part.In the case of a permanent magnet, each atom has a tiny magnet, with its own north pole and south pole.
