3. With the switch open try to pick up some paper clips and tacks. What happens?4. Close the switch and try to pick up the same paper clips and tacks. What happens?You can increase the power of your electromagnet by winding more turns of wire around the nail. You could also use ...
Explore the powerful engineering of electromagnets in this fun and easy electricity project. LearnHow to Make an Electromagnet! Plus, learn why electromagnets are important in our race to reduce our dependence on fossil fuels… They’re the key to electric cars! Electric and hybrid vehicles use e...
Here, an electromagnet is used to pick up some of the approximately 3,500 confiscated guns to be melted down. David McNew/Getty Images 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 ...

NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
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 ...
If you want more of an experiment but don’t want to make a complete electromagnetic crane, a simple demonstration, with this experiment from Study.com, can reveal which factors affect the strength of an electromagnet. Get two (or more) batteries, some electric wire, a nail (at least 3 ...
Even in the present day, manufacturers are tinkering with the instrument panel, moving it to the center of the dashboard or packing it full of technology that may make keeping your eyes on the road harder than ever. Sources Barron, James. "Rethinking Design of Car Dashboards." New York ...
Adynamic microphonetakes advantage of electromagnet effects. When a magnet moves past a wire (or coil of wire), the magnet induces current to flow in the wire. In a dynamic microphone, the diaphragm moves either a magnet or a coil when sound waves hit the diaphragm, and the movement create...
You obviously need a stronger electromagnet for a particle collider than you do for a speaker, so how do scientists make magnets powerful enough to focus a beam of electrons? The answer is a bit more complicated than simply making them bigger, although that's part of it. The materials you...
