What kind of magnet can vary its strength and polarity?
An electromagnet can vary its strength and polarity by controlling the flow of electric current through its coil. By changing the direction and intensity of the electrical current, an electromagnet can easily adjust its magnetic field characteristics.
What kind of energy does an electromagnet make?
An electromagnet produces magnetic energy when an electric current flows through its coil, creating a magnetic field around it.
What kind of magnet can attract steel and iron due to electricity?
An electromagnet can attract steel and iron due to electricity. When an electric current flows through the coil of wire in an electromagnet, it creates a magnetic field that can attract ferromagnetic materials like steel and iron. The strength of the magnetic field can be controlled by adjusting the amount of electric current flowing through the electromagnet.
What kind of energy transformation takes place in electromagnet?
Electrical energy is transformed into magnetic energy in an electromagnet. When an electric current flows through the coil of wire, a magnetic field is created, allowing the electromagnet to attract or repel other magnetic objects.
How does a electromagnet differ from permament magnet?
an electromagnet performs its magnetic property only when it is conducted with currents(either direct current or alternating current) while the permament magnet is the kind of material which show its magnetic property in the common situation.
Earth is a what kind of magnet?
Apparently an electromagnet, if that's what you mean, since the current is believed to be the result of currents flowing in Earth's interior.
What kind of magnet is an electromagnet?
An electromagnet is a piece of iron(usually a cylinder or rectangle)wrapped around with copper wire that when electricity runs through it it works like a magnet. Also called artificial magnet.
What kind of magnet is electromagnet?
An electromagnet is a piece of iron(usually a cylinder or rectangle)wrapped around with copper wire that when electricity runs through it it works like a magnet. Also called artificial magnet.
What kind of magnet is used in the hotel room door?
Electro Magnetic is correct
What kind of energy does an electromagnet use?
electromagnetism
What kind of wire can be used to make a magnet?
A copper wire can be used to make an electromagnet by wrapping it around a magnetic core material such as iron. When an electric current flows through the wire, it creates a magnetic field around the wire, which magnetizes the core material.
What kind of magnet can vary its strength polarity?
an electromagnet
