Statement B: Pot shaped magnets are in the loud speakers

• A. A true, B true
• B. A false, B true
• C. A false, B false
• D. A true, B false

Answer 1

The correct option is A A true, B true

1. A magnet is a material or object that produces a magnetic fiels This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic material, such as iron, steel, nickel, cobalt etc. and attracts or repels other magnets.

2. A horse shoe magnet is stronger because both poles of the magnet are closer to each other and in the same plane which allows the magnetic lines of flux to flow along a more direct path between the poles and concentrates the magnetic field.

3. A pot magnet is a permanent magnet encased in a steel shell, which is sometimes called a pot, hence the name pot magnet.

$\text{Hence A is the correct option}$
