NEET Physics (general) MCQ Question
Which of the following statements about the relationship between electricity and magnetism is correct?
Electric charges in an atom are influenced by magnetic fields, as shown in the Zeeman effect.
Magnetic fields only affect moving charges and not stationary charges.
The Lorentz transformation equations were derived to explain the interaction of electric fields only.
The existence of electric charges in the atom was postulated after the discovery of magnetic fields.
Correct Answer
Detailed Explanation
Statement A is correct as it relates to the Zeeman effect, which involves the interaction of magnetic fields with electric charges. Statement B is misleading as magnetic fields can also affect stationary charges indirectly. Statement C incorrectly limits the Lorentz transformation to electric fields, while D misrepresents the historical context of electric charges and magnetic fields.
