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.

What type of energy is created when moving a magnet through a coil of wires?
The type of energy created is electrical energy. As the magnet moves through the coil of wires, it induces an electric current to flow through the wires, generating electrical energy.
How does an electric generator work to convert mechanical energy into electrical energy?
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.
Is the magnet in a compass a permanent or electromagnet?
The magnet in a compass is a permanent magnet. It retains its magnetism without the need for an external electrical current.
How does a magnet affect the electrical current?
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.
What is electrical method of making magnet?
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.
What type of energy is created when moving a magnet through a coil of wires?
The type of energy created is electrical energy. As the magnet moves through the coil of wires, it induces an electric current to flow through the wires, generating electrical energy.
How can a magnet be used to create an electric current?
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.

What is a temporary magnet caused by an electrical current?
A Electro Magnet, caused in theory by the alignment of the particles in the material duo to the current passing through it.

How can you use a magnet to induce a current?
You can induce a current in a wire by moving the magnet in and out of the coil or by moving the coil near the magnet. The changing magnetic field created by the moving magnet induces a current in the wire according to Faraday's law of electromagnetic induction.
