Answer key
Show suggested answers
- A magnetic field is the region around a magnet or current-carrying conductor where magnetic force can be experienced.
- Magnetic field lines emerge from the north pole and enter the south pole outside a magnet. They do not intersect each other.
- Right-hand thumb rule: If the thumb points in the direction of current, curled fingers show the direction of magnetic field lines.
- A magnetic field is produced around a current-carrying conductor.
- Fleming's left-hand rule gives the direction of force on a current-carrying conductor placed in a magnetic field.
- An electric motor works on the principle that a current-carrying conductor experiences force in a magnetic field.
- An electromagnet is a temporary magnet produced by current flowing through a coil.
- Electromagnets are used in electric bells, cranes, relays, and magnetic separation devices.
- A fuse protects a circuit by melting and breaking the circuit when current becomes too high.
- Earthing provides a safe low-resistance path for leakage current to flow into the ground.
How to use this worksheet
Students can solve the questions independently first, then review errors with a parent or teacher. Teachers can use it as a short class activity, homework sheet, or revision check.
