2. A magnet is removed from a refrigerator door and placed on a table. In 1–2 sentences, explain how the potential energy of the system changes in this process. (2 points)

3. Using a simple model of an electromagnet, describe the factors that increase the magnetic field strength of an electromagnet.(2 points)

Sagot :

Answer:

1. at least two charged interacting parts

2. from the electric fields of charged subatomic particles

3 an arrow released from the bow

4Electrical fields of charged particles interact, bonding those with opposite charges.

5 the interaction of the electric fields of protons and electrons

6 The energy stored in the system increases.

7 Kinetic energy increases because the magnets move in the direction of the field.

8 Iron pieces accelerate toward the magnet, and the energy stored in the system decreases.

9  

The energy stored in the field decreases because the magnet moves in the direction of the field.

10 The energy stored increases and then decreases.

11 The wire was not connected to the source.

12  The electromagnet will become more powerful.

the rest are written, hope this helps (:

Particle accelerator, propel charge, removing magnet from refrigerator increases potential energy and factor increase magnetic field are a number of turns and current.

What is magnetic field?

The magnetic field is the field in the space and around the magnet in which the magnetic field can be filled.

Magnetic force is the force of attraction of repulsion between two poles of the two magnets. The magnetic force also appears between two electrically charged bodies.

  • 1. Describe how a particle accelerator works and give an example of the applications of the discoveries made with them.

Particle accelerator is a machine which is used to propel charge particles and produces high beam of these charge particles like electron or proton by using the electromagnetic field.

The application of particle accelerator in the field of medical for the treatment of cancer.

  • 2. A magnet removed from a refrigerator door and placed on a table. Explain how the potential energy of the system changes in this process.

When the magnet removed from the refrigerator door, the potential energy of the system increases, as the momentum of these two poles part, reduces the influencing force.

  • 3. Using a simple model of an electromagnet, describe the factors that increase the magnetic field strength of an electromagnet.

Factors that increase the magnetic field strength of an electromagnet are,

  • a) Number of turns-When the number of turns of the winding of electromagnet is increases, then the strength of magnetic field also increases.
  • b) Current-When the amount of current in the solenoid of electromagnet is increases, then the strength of magnetic field also increases.
