Can u turn an electromagnet on and off?

Stars produce their own energy through fusion reaction of gasses. They are like gas burning orbs. The star of our solar system is the Sun because of the fusion reaction of Helium and hydrogen.

Why is electromagnetism important in today's technology?

Electromagnetism has important scientific and technological applications. It is used in many electrical appliances to generate desired magnetic fields. It is even used in a electric generator to produce magnetic fields for electromagnetic induction to occur. Keeping this in consideration, what are the 3 components needed for electromagnetism? There are three main parts required to build an electromagnet: the iron core, copper wire, and an electricity source. Changes in each of these pieces of the electromagnet will influence the overall strength of the magnet.

How do you explain electromagnetism to a child?

The word ""electromagnetism"" in physics is used to describe one of the fundamental forces of nature. This force is between subatomic particles such as protons and electrons. It helps to hold matter together. Electromagnetism is also used to describe how a magnetic field is created by the flowing of electric current. Subsequently, is a battery an electromagnet? The electric current from the battery caused the nail to have a magnetic field around it. This magnetic field made the nail act as a magnet (an effect). It became an electromagnet.


How do you make an electromagnet with a battery?

A model of the universe in which there is not enough mass to counteract the expansion by means of attraction.

You can also ask what is electromagnet give three uses of electromagnet?

Uses of electromagnet: Electromagnets are used in a number of electric appliances such as electric bells and electric buzzers. They are used in electric motors, which find wide application in fans, washing machines etc. Very strong electromagnets are used in factories and cranes for lifting heavy iron pieces. Keeping this in consideration, what are electromagnetic activities? Cyber electromagnetic activities are activities leveraged to seize, retain, and exploit an advantage over adversaries and enemies in both cyberspace and the electromagnetic spectrum, while simultaneously denying and degrading adversary and enemy use of the same and protecting the mission command system (ADRP 3-0).
