By making the magnetic field around it a negative charge
An electric current produces a magnetic field.
An electromagnet is temporary because the field disappears when the current is switched off.
Current flow
Yes.
Electromagnet. Magnetic only when current is flowing in the coil.
An electric current produces a magnetic field.
If it has been magnetized by another magnet, then it is just a temporary magnet, but if it uses an electric current, then it is an electro-magnet.
the write sentence for the word is a temporary magnet caused by an electric current
Electromagnets have temporary nature because if you take away their electric current, the magnet no longer works.
When iron is passed through an electric current, it can be attracted to steel because it has became a temporary magnet
Unit 8, Lesson 7. Do your work.
An electromagnet is temporary because the field disappears when the current is switched off.
By making the magnetic field around it a negative charge
Current flow
Electro-Magnet
The strength of a magnet(electromagnet) made by flowing electric current through a conducting coil depends on magnitude of current. . .
the electric current is generated by the electric field. thus by the left hand rule when current is passed through a conductor a magnetic field is generated around it so that it is a similar act of a magnet. thus it seems to be a magnet.
