Printable Magnets Vocabulary Worksheet. Science Definitions. Electricity & Magnetism: Magnets. A magnet is an object or a device that gives off an external magnetic field.
Basically, it applies a force over a distance on other magnets, electrical currents, beams of charge, circuits, or magnetic materials. Magnetism can even be caused by electrical currents. While you might think of metal magnets such as the ones you use in class, there are many different types of magnetic materials. Iron (Fe) is an easy material to use. Other elements such as neodymium (Nd) and samarium (Sm) are also used in magnets. There are many different types of magnets. Most of the magnets you see around you are man-made. There are also air-core magnets. Electromagnets are different because they have a ferromagnetic material (usually iron or steel) located inside of the coils of wire.
Electricity & Magnetism: Magnetic Fields. Magnetic fields are different from electric fields.
Although both types of fields are interconnected, they do different things. The idea of magnetic field lines and magnetic fields was first examined by Michael Faraday and later by James Clerk Maxwell. Both of these English scientists made great discoveries in the field of electromagnetism. Magnetic fields are areas where an object exhibits a magnetic influence. The fields affect neighboring objects along things called magnetic field lines. If you place an object in a magnetic field, it will be affected, and the effect will happen along field lines.

The topics and activities in each age group are ideal for learners of those ages. If you have any feedback, please share it with us below! What is a magnet? A magnet is any object that generates its own magnetic force, called a magnetic field. The ancient Greeks discovered that some rocks, known as lodestones, produced their own magnetic field. Magnets come in many shapes and sizes and can be made from different types of material but only metals are magnetic. How do magnets work?
Magnets can attract other materials. When two magnets are placed together one magnet’s north pole will attract the other’s south pole. Which materials are magnetic? Some magnets are stronger than others. Did you know that planet Earth is a big magnet? Did you know the Earth actually produces its own magnetic field? What is a compass?

How Electromagnets Work" What do a wrecking yard, a rock concert and your front door have in common?
They each use electromagnets, devices that create a magnetic field through the application of electricity. Wrecking yards employ extremely powerful electromagnets to move heavy pieces of scrap metal or even entire cars from one place to another. Your favorite band uses electromagnets to amplify the sound coming out of its speakers. And when someone rings your doorbell, a tiny electromagnet pulls a metal clapper against a bell. Mechanically, an electromagnet is pretty simple. Before we go too much farther, we should discuss how electromagnets differ from your run-of-the-mill "permanent" magnets, like the ones holding your Popsicle art to the fridge. The doorbell is a good example of how electromagnets can be used in applications where permanent magnets just wouldn’t make any sense. Fun Magnet Facts For Kids.
