Unit 3 Revision - Fields Quiz

What is an electric field?

• An electric field is a region around a magnet within which a force would be exerted on other magnets.

• An electric field is a region around a conductor within which a force would be exerted on other conductors.

• An electric field is a region around a charged particle or object within which a force would be exerted on other charged particles or objects.

• An electric field is a region around a non-charged particle or object within which a force would be exerted on other non-charged particles or objects.

What is the SI unit of electric field?

• V/m

• N/C

• J/C

• A/m

How is the direction of an electric field represented?

• By the direction of the force experienced by a positive test charge placed in the field.

• By the direction of the force experienced by a negative test charge placed in the field.

• By the direction of the magnetic field surrounding the electric field.

• By the direction of the electric current flowing through the field.

What is the formula to calculate the electric field strength?

• E = F + q

• E = F - q

• E = F * q

• E = F / q

What is a magnetic field?

• A magnetic field is a region in space where gravity can be detected.

• A magnetic field is a region in space where sound waves can be detected.

• A magnetic field is a region in space where electric charge can be detected.

• A magnetic field is a region in space where a magnetic force can be detected.

What is the SI unit of magnetic field?

What is the formula to calculate the magnetic field strength?

• B = μ0 * (I / (2πr))

• B = μ0 * (I / (2πr^4))

• B = μ0 * (I / (2πr^3))

• B = μ0 * (I / (2πr^2))
