<u>Answer:</u>
A piece of soft iron is placed in a solenoid increasing the magnetic field in an arrangement that can be switched on and off. Such a device is called an electromagnet.
<u>Explanation:</u>
When a magnet is processed by supplying electricity than it is called as electromagnet and therefore its strength can be fluctuated as dependent on amount of electricity supplied.
Here, when a iron piece is moved closer to a long coil of wire named solenoid physical interaction named electromagnetic force take place between two electrically charged particles.
This force is supplied by electromagnetic fields constructed from electric and magnetic field. This is also called as Lorentz force constituted from both electricity and magnetism. This property itself gives evidence of characteristics of material used for electromagnetism.
Answer:
01) Asteroids are formed closer to the sun than comets.
Explanation:
Majority of asteroids are present region between Jupiter and Mars while the comets are found away from the orbits of Pluto and Neptune.
