Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A moving electric charge produces____
A
Only electric field
B
Only Magnetic field
C
Both electric and magnetic field
D
Either electric or a magnetic field
Explanation: 

Detailed explanation-1: -This contradiction can be overcome by assuming a new force is generated when the electron is moving. Therefore, we can say that the moving charge produces both electric and magnetic fields. Therefore, the correct answer is option C. Note: The moving electron alone does not produce the magnetic field.

Detailed explanation-2: -1820-Electromagnetism, Current In 1820, a physicist Hans Christian Oersted, learned that a current flowing through a wire would move a compass needle placed beside it. This showed that an electric current produced a magnetic field.

Detailed explanation-3: -As Ampere suggested, a magnetic field is produced whenever an electrical charge is in motion. The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire.

Detailed explanation-4: -A stationary charge produces only electric field whereas a moving charge produces both electric as well as magnetic fields.

Detailed explanation-5: -Both electric and magnetic fields are the consequence of the attraction and repulsion of electric charges. However, a magnetic effect is caused by moving electric charges while an electric field is caused by stationary charges.
