Which of the following statements are correct?

A. Moving charges produce a magnetic field in the surrounding space.
B. An instrument called the current balance is used to measure mechanical force between two parallel conductors.
C. The electron has an intrinsic magnetic moment, which is known as the orbital magnetic moment.
D. Magnetic field of several sources is the vector addition of magnetic field of each individual source.
E. The radius of the circular component of motion is called the radius of the helix.

Choose the correct answer from the options given below:

A, B, D and E Only

Moving charges or current produces the magnetic field.

The current balance measures current by measuring the force between two parallel wires carrying that current.

The electron has an intrinsic magnetic moment, which is known as the spin magnetic moment.

Magnetic field of several sources is the vector addition of magnetic field of each individual source.

The radius of the circular component of motion is called the radius of the helix.
