Want this question answered?
a) The production of an electric or magnetic state by the proximity (without contact) of an electrified or magnetized body. b) The production of an electric current in a conductor by a change of magnetic field.
Electric guitars are not magnetized, they use pickups designed to feel the vibration of the string and the signal is then amplified. It is the amplifier that is highly magnetic.
a magnet that remains magnetized for only a small time interval as compared to a permanent magnet.
When you will rub a thing that magnet attracts on magnet than the magnetic particles will transmitted into that thing and that thing becomes magnet.For example:when you will rub a pin on magnet than it will also become magnetic and it will attract other pins also.

Electromagnet perhaps?
magnetized
No. The strength of the electric field remains unchanged regardless of your proximity. However, the effects of the electric field on you are more pronounced as you move closer to it.
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.
A magnetic field is induced by moving electric charges, either by an actual electric current, or the way that electrons (charged particles) spin around the nucleus [in the case of magnetic materials becoming magnetized].
This is called an elecro-magnet, and it is only magnetized while current is running through it.
electromagnetic crane has a huge electic magnet instaed of a hook. this magnet is operated by an electrical current. when electric is switched on the magnet becomes magnetized,allowing metal objects to be picked up just like an ordinary magnet.when elctric is turned off the metal object will fall away, as it is no longer magnetized.
