Why are electromagnets used?Why does the length of current loop affect the magnetic force?Why must soft iron be used with an electromagnet?Suppose that a (small) charged conductor is connected to the ground. Explain why the conductor becomes uncharged.Why are magnetic field lines closed curves?
Electromagnets are created by running an electrical current through a conductive metal. An electrical current causes the rapid movement of electrons, which creates a magnetic field. Electromagnetic fields can be created by running an electrical current through any metal, including non-ferrous conductive ...
Specimens are cut into extremely thin sections, and the transmission electron microscope aims an electron beam through a section, just as a light microscope aims a beam of light through a specimen. However, instead of lenses made of glass, the transmission electron microscope uses electromagnets as...
