Who founded and named the science of electromagnetism?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4, i.e. Andre Marie Ampere.
The scientist who founded and named the science of electromagnetism is Andre Marie Ampere.
While other scientists like Hans Christian Oersted made key discoveries in electromagnetism by observing the connection between electricity and magnetism, it was Ampere who formally established and named the field with his theoretical work on the relationship between electric currents and magnetic fields.
Other options:
- James Clerk Maxwell: Although Maxwell significantly contributed to the understanding of electromagnetism by developing a unified theory encompassing light, electricity, and magnetism, he did not 'found' or name the field.
- Hans Christian Oersted: While Oersted's discovery of the magnetic field produced by an electric current was pivotal, he did not name the field itself.
- Michael Faraday: Faraday is known for his important discoveries in electromagnetism, particularly electromagnetic induction. However, he did not name the field.
