Question

Намагниченная стальная линейка одним концом прижата к столу.Линейку отогнули к низу и опустили .Будет ли линейка излучать электромагнитные волны?Если будет,то каков механизм их образования?

Answer 1

Если заряженную линейку привести в колебательное движение то линейка будет излучать электромагнитные волны потому что при колебательном движении и линейка и заряды двигаются с ускорением

Answer 2

Can a magnetized steel ruler emit electromagnetic waves when bent and lowered?

When a magnetized steel ruler is bent and lowered, it will not emit electromagnetic waves. The mechanism of electromagnetic wave generation involves the acceleration of charged particles, such as electrons. In the case of a magnetized steel ruler, there is no significant movement or acceleration of charged particles that would result in the emission of electromagnetic waves.

Electromagnetic waves are typically generated by accelerating charged particles, such as in the case of an antenna or an electric current flowing through a wire. When these charged particles are accelerated, they create oscillating electric and magnetic fields that propagate through space as electromagnetic waves.

In the scenario described, where a magnetized steel ruler is bent and lowered, there is no significant acceleration of charged particles. The bending and lowering of the ruler do not involve any movement or acceleration of charged particles that would result in the emission of electromagnetic waves.

Therefore, the magnetized steel ruler will not emit electromagnetic waves in this situation.
