Front

What is the law of attraction in magnetism?

Back

Opposite poles attract, like poles repel.

Front

What is an electromagnet?

Back

A magnet created via electric current.

Front

What happens to the intensity of a light bulb in a series circuit if another bulb is added?

Back

The intensity decreases.

Front

What is a magnetic field?

Back

The region around a magnet where magnetic force acts.

Front

What is static electricity?

Back

The build-up of electric charges on the surface of an object that may result in a shock.

Front

What is the difference between conductors and insulators?

Back

Conductors allow electric current to flow easily, while insulators resist the flow of electric current.

Front

What is Ohm's Law?

Back

The relationship between voltage (V), current (I), and resistance (R) in a circuit: V = I × R.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is kinetic energy?

Back

The energy of an object due to its motion, calculated as KE = 1/2 mv².

Front

What is potential energy?

Back

The energy stored in an object due to its position or configuration, often related to height.
