Final answer:

The false statement about the relationship between electricity and magnetism is that all magnets are surrounded by an electrical field. This is untrue, as they are surrounded by magnetic fields.

Step-by-step explanation:

The correct answer to the question "Which of the following is NOT true about the relationship between electricity and magnetism?" is b. All magnets are surrounded by an electrical field. This statement is false because magnets are primarily surrounded by magnetic fields, not electrical fields. While it is true that moving magnetic fields can induce electrical currents, a stationary magnet alone does not generate an electrical field.

Contrarily, motors indeed use electrical currents to create a magnetic field that exerts a torque on wire loops, causing rotation and converting electrical energy to mechanical energy. Similarly, a magnetic field can indeed induce an electrical current, a phenomenon crucial in the operation of generators, which convert mechanical energy into electrical energy using magnets.
