To make a magnet repel a metal, one must first understand the properties of a magnet. A magnet has two poles, a north pole and a south pole. When magnets are placed near each other, opposite poles attract and like poles repel one another. When a metal enters a magnetic field, all of...

In a strong magnetic field, some walls disappear entirely. The resulting magnet's strength depends on the amount of force used to move the domains. Its permanence, or retentivity, depends on how difficult it was to encourage the domains to align. Materials that are hard to magnetize generally...
I'm not going to use the Earth's North and South poles to magnetize my circular magnet, but instead, a very powerful solenoid wrapped around it. Jun 16, 2016 #85 Charles Link Homework Helper Insights Author Gold Member 5,847 3,075 Part Toon said: I don't think you quite ...
Did you know that you can take away the sticking power of a permanent magnet by dropping it? The impact can actually cause the atoms to fall out of alignment. You can magnetize them again by rubbing a magnet on it. Putting the 'Electro' in 'Electromagnet' Since you need an electrical...
By the 12th century, people had discovered that they could use lodestone to magnetize pieces of iron, creating a compass. Repeatedly rubbing lodestone along an iron needle in one direction magnetized the needle. It would then align itself in a north-south direction when suspended. Eventually, sci...
But you don't have to wait for a storm to bring an electromagnet to life. A current is introduced, either from a battery or another source of electricity, and flows through the wire. This creates a magnetic field around the coiled wire, magnetizing the metal as if it were a permanent ...
You can think of your ecommerce store as a central hub for your brand, to magnetize audiences and build trust with shoppers. Selling online requires a balancing act between technology, marketing strategy and human operations. You can think of a digital storefront as a virtual space where you...
In a typical reed switch, the two contacts (which look like metal reeds) are made from a ferromagnetic material (that means something as easy to magnetize as iron), plated with a hardwearing metal such as rhodium or ruthenium (to give them a long life as they switch on and off), and...
Learning to visualize the flow of individual electrons was a breakthrough for me in understating tube amplifier electronics.Electric guitars generate an alternating current (AC) audio signal. The guitar's pickups are small electric generators. Pickups have magnets (poles) that magnetize the metal ...
