FAQs on Magnetic Fields Video Lecture - Physics for GCSE/IGCSE - Class 10
| 1. What is a magnetic field? |  |
Ans. A magnetic field is a region surrounding a magnet where magnetic forces are experienced. It is produced by moving electric charges and is characterized by the direction of the force it exerts on other magnetic materials.
| 2. How is a magnetic field formed? | |
Ans. A magnetic field is formed when electric charges move. In a permanent magnet, the electrons orbiting the atoms all align in the same direction, creating a magnetic field. In electromagnets, passing an electric current through a wire generates a magnetic field.
| 3. How does a magnetic field affect nearby objects? | |
Ans. A magnetic field can exert forces on nearby objects made of magnetic materials, such as iron. These objects will be attracted or repelled depending on the orientation of the magnetic field and the object.
| 4. What are the applications of magnetic fields in everyday life? | |
Ans. Magnetic fields are used in various technologies, such as generators, motors, and transformers. They are also used in magnetic resonance imaging (MRI) machines in medicine and in magnetic compasses for navigation.
| 5. How can the strength of a magnetic field be increased or decreased? | |
Ans. The strength of a magnetic field can be increased by increasing the current in an electromagnet or by adding more coils to the wire. It can be decreased by moving the magnet farther away from the object or by reducing the current flow.
