What is a control test tube?
There are many uses of the electromagnet, it is used to invent generators and electric motors, used it to control the switch relay, use in practical industries, and even in an electric bell etc. Because the electromagnet is a type of magnet in which the magnetic field is produced by the electric current.
How does an electric motor look like?
A bar magnet is any RECTANGULAR object that has a magnetic field.It can be made out of any ferromagnetic substance, but it is mainly made out of iron or steel. Most of the time, a bar magnet is a pernament magnet, meaning it does not need an electric current in order for it to retain its magnetism.
What type of motor is used to operate such devices as fuel pumps or wind shied wipere?
Most are electric motors.
How can magnets contribute in your society?
Magnets are very important to us. without a magnet there is not even a single electric machine is found....... magnet is used in electronics also for example PC hard disk;windmill,speakers,motors ,generators,etc.........................
