The magnetic field produced by an electric current either points towards the current or away from the current, depending on the direction of the current. (section 20. 2).

Respuesta :

The electric field direction about a positive source charge always point away from the positive charge and towards a negative charge.

Direction of the electric field due to positive charge

Electric field is a vector quantity that a positive test charge would be repelled when placed in the field.

Thus, the electric field direction about a positive source charge always point away from the positive source.

Direction of the electric field due to negative charge

The electric field direction about a negative charge always point towards the negative source.
