Designing a small-scale flying robot posed significant challenges. Traditional flying robots rely on onboard power sources ...

A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.

It explains how electrons are accelerated by an electron gun and then deflected by a magnetic field created by Helmholtz coils. The experiment measures the mass of an electron by analyzing the ...
