: a core of magnetic material (such as iron) surrounded by a coil of wire through which an electric current is passed to magnetize the core.
What is an electromagnet in simple words?
Word forms: plural electromagnets. countable noun. An electromagnet is a magnet that consists of a piece of iron or steel surrounded by a coil. The metal becomes magnetic when an electric current is passed through the coil.
What is the definition of electromagnetic for kids?
Kids Definition of electromagnetic
: of or relating to a magnetic field produced by an electric current. electromagnetic.
What is an electromagnet for Class 7?
Answer: An electromagnet is a coil of insulated wire wound around a piece of a magnetic substance such as soft iron. The magnetic substance acts as a magnet as long as the current flows in the wire.
What is electromagnet class 10th?
An electromagnet is a temporary magnet which behaves like a magnet when an electric current is passed through the insulated copper wire and loses its magnetism when current is stopped. It has a soft iron piece called the core with an insulated copper wire wound on it.
What is a electromagnet in physics?
An electromagnet is a magnet made with electricity. Normal magnets are called permanent magnets. An electromagnet has the same properties as an ordinary magnet. … It is different from a permanent magnet because it can be turned on and off. When electricity flows in a circle of wire, it makes a magnet.
What is an electromagnet write its one use?
An electromagnet is a device that sends electricity through a coil of wire to produce a magnetic field. … Electromagnets are used in millions of devices around the world, from hard disk drives and MRI machines, to motors and generators.
How is an electromagnet made Class 10?
The insulated copper wire is wrapped on a soft iron piece. When current is passed through the coil using a battery and a key the iron piece behaves like a bar magnet as long as current is being passed. Such a magnet is called an electromagnet.
What is electromagnet explain with diagram?
The insulated copper wire is warpped on a soft iron piece. When current is passed through the coil using a battery and a key the iron piece behaves like a bar magnet as long as current is being passed. Such a magnet is called an electromagnet.
How is an electromagnet made Class 6?
Answer: An electromagnet is made by wrapping a coiled wire around a rod of iron. Magnetic strength increases with the increase in number of turns in the coil.
What is electromagnet and how it is formed?
Electromagnets are magnets that are generated by electric fields. … Electromagnets can be created by wrapping a wire around an iron nail and running current through the wire. The electric field in the wire coil creates a magnetic field around the nail.
How is an electromagnet made answer?
An electromagnet is made by winding an insulated copper wire around a soft iron core either in the shape of a solenoid or U-shape and passing current through it. The strength of magnetic field of an electromagnet depends on: The number of turns of wire wound around the coil, and.
