Q:

What is a U-shaped magnet?

A:

Quick Answer

A U-shaped magnet derives its name from its shape and has both a north and a south pole located in the same plane at the open end of the magnet. This type of magnet is also called a horseshoe magnet.

Full Answer

The magnetic lines go from pole to pole in a magnet. In a U-shaped magnet, most of the magnetic field is in the area between the two poles, but the magnetic lines travel through the rounded area of the U as well. Because both poles are pointing in the same direction, the U-shaped magnet has more lifting strength, attracting objects to both poles. This type of magnet is a permanent magnet and does not require a current to operate.

  • Q:

    What are the different types of magnets?

    A:

    Based on magnetic properties, there are three major types of magnets: permanent, temporary and electromagnets. Permanent magnets retain their magnetism once magnetized while temporary magnets only exhibit magnetic properties whenever they come within range of a magnetic field, and only for a short period. Electromagnets are magnets that only display magnetic properties when current passes through their core.

    Is titanium magnetic?

    A:

    Titanium is considered paramagnetic, as it has no standing magnetic field of its own, but it develops one in the presence of an externally applied magnetic field. According to the University of Maryland, titanium is able to induce an electrical current in some metals, but only weakly.

    Can electromagnetic waves travel through a vacuum?

    A:

    According to the BBC, electromagnetic waves can move freely through a vacuum, as they do not need to travel through matter. In fact, although a slight difference between speeds exists, electromagnetic waves travel faster in a vacuum than through matter.

    What is an AC generator?

    A:

    An AC generator, also called an alternator, is a device that converts mechanical energy into electrical energy. "AC" stands for "alternating current." The device generates alternating voltage by rotating a coil in the magnetic field.
