Give two different properties of a current-carrying coil and state Ampere's suggestion.
(N/A) current-carrying coil exhibits the following properties:
$(1)$ It produces a magnetic field and behaves like a magnetic dipole at large distances.
$(2)$ It experiences a torque when placed in an external magnetic field,similar to a magnetic needle.
- Based on these observations,Ampere suggested that all magnetism is due to circulating currents.
- This hypothesis is partially correct,as no magnetic monopoles have been observed to date.
- However,elementary particles like electrons and protons possess an intrinsic magnetic moment that cannot be explained solely by circulating currents.
