How do you make a powerful magnet?
To make a powerful magnet, use a strong magnetic material like neodymium. Shape it into a magnet by applying a magnetic field while it cools down. Finally, the magnet can be magnetized by rubbing it against a magnet or by exposing it to an electrical current.
Can you make energy using a magnet?
There is really no way to make energy - do some reading about the Law of Conservation of Energy for more details. With a magnet, you can convert one type of energy into another - mechanical energy into electrical energy, or electrical energy into mechanical energy.
Describe the energy transformation that takes place in a generator?
Mechanical energy to electrical energy. A generator consists of a large magnet placed inside a coil of wire. . When the magnet is rotated (mechanical) it impels the electrons in the wire to move(electrical). Conversely, with suitable electrical engineering, when a magnet is placed inside a wire coil and electricity is passed through the wire, it will make the magnet rotate.
What is true about the magnet if an electric field exists around a magnet?
Then the magnet not only has magnetism, but also an electrical charge.
Why must you make a magnet by using batteries?
because battery supplies a direct current and to make a magnet with using the electrical method you need to supply direct current to the material {metal}which must be wounded with a coil {solenoid}.
What is the name of a magnet made using the electrical?
That is an electromagnet.
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.
In building an electrical generator does the the magnet have to touch the spinning copper or does it not matter?
no, magnet needs to be close to winding, not touching it
Why poles of the magnet can't be separaed?
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.
What energy is produced when a coiled wire is spun around a magnet?
Electrical
Is a north or south magnet in a compass a permagnet or an electromagnet?
That's a permanent magnet. After all, the compass doesn't need an electrical current, right?That's a permanent magnet.

After all, the compass doesn't need an electrical current, right?
How can magnet produce current?
Faraday found that a wire passed by a magnet induces a current in the wire. This led to making an electrical generator.
