FAQs on Introduction to Magnetism Video Lecture - Physics for JAMB
| 1. What is magnetism? |  |
Ans. Magnetism is a natural phenomenon where certain materials, such as iron, exhibit attractive or repulsive forces on other objects. It is caused by the alignment of electrons in the material, creating a magnetic field.
| 2. How does magnetism work? | |
Ans. Magnetism works due to the movement of electric charges. When the electrons in a material align in the same direction, they create a magnetic field. This field can attract or repel other magnetic materials.
| 3. What are the types of magnets? | |
Ans. There are three main types of magnets: permanent magnets, temporary magnets, and electromagnets. Permanent magnets retain their magnetism, temporary magnets can be magnetized temporarily, and electromagnets are magnets created by passing an electric current through a coil.
| 4. What are the practical applications of magnetism? | |
Ans. Magnetism has various practical applications, such as in electric motors, generators, MRI machines, compasses, magnetic storage devices like hard drives, and magnetic levitation trains. It is also used in everyday objects like speakers and refrigerator magnets.
| 5. How can magnets be demagnetized? | |
Ans. Magnets can be demagnetized by exposing them to heat or strong magnetic fields that disrupt the alignment of their electrons. Additionally, dropping or striking a magnet can also cause it to lose its magnetism.
