Answer to Question #308786 in Electricity and Magnetism for Kell

Question

Which of the following activities would lead to the creation of magnetic fields?

a. Placing a positive ion in an environment where it has zero acceleration and a zero velocity

b. Placing a proton in an environment where it is moving at 2 m/s in a straight line

c. Placing a positive ion in an environment where it is completely at rest d. Placing the nucleus of an atom in an environment where it has zero acceleration and a nonzero velocity

e. Placing an electron in an environment where it has a nonzero acceleration that is constantly changing

Answer 1

Answer

when the charge is accelarated then which it produces electromagnetic field in electric field & magnetic field depends on each other.

When the velocity then charge moves with constant It produces which does not depends on electric field. velocity => non-zero magnetic field Accelaration → zero

There option c is correct.
