Current flowing through a conductor will produce which two effects?

When current flows through a conductor, it generates both heat and a magnetic field due to the principles of electromagnetism and resistive heating.

The heat produced is a result of the resistance in the conductor, described by Joule's Law, which states that the power of the heat generated (in watts) is equal to the square of the current (in amperes) multiplied by the resistance (in ohms). This indicates that the greater the current or resistance, the more heat will be produced.

Simultaneously, an electric current creates a magnetic field around the conductor. This phenomenon is explained by Ampère's Circuital Law, which establishes that the magnetic field is directly proportional to the current flowing through the conductor. This magnetic field can be harnessed and is fundamental in the operation of devices like transformers and electric motors.

Therefore, the correct choice highlights these two essential effects of electric current in conductors: the generation of heat and the establishment of a magnetic field.
