Electromagnets are found in doorbells, hard drives, speakers, MagLev trains, anti-shoplifting systems, MRI machines, Microphones, home security systems, VCR's, tape desks, motors, and many other everyday objects

The moving charges through the wire create a magnetic field. A weak electromagnet uses a straight wire, but to make it stronger, you can make more current run through the system (by increasing battery voltage or decreasing resistance) or by coiling the wire. The more you coil a wire, the stronger the magnetic field will be.

Here is a diagram of a basic electromagnet using a battery, a nail, and a coiled wire:

This deflection convinced him that magnetic fields radiate from all sides of a wire carrying an electric current, just as light and heat do.

Also the modern way of locking the door or a bank safe is to have a magnetic locking device. Either they may be having a number secret code or a magnetic card which when swiped opens the door. The number keys are stored in the magnetic tape on the back of the card, interacts with the magnetic card reader in the door. When the data stored on the card and the memory matches, the door opens. Similar principle is used in the bank’s safe lockers.

Books, as heavy as hundreds of kilograms can be stored in few milligrams of memory stick. The data are stored in electromagnetic format in the form of bits and bytes. Even the computer hard ware is having a magnetic tape which works on the electromagnetic principle. Not limiting to this, the olden day VCR’s and VCP’s are having huge rolls of magnetic tapes, which had data in it. This can be recorded or read by electromagnetic means only. Also the computer and Televisions use high current electromagnets to produce a beam of electrons from the cathode ray tube. However now a days we use LCD’s and Plasma types.

The interaction of the signals and the electromagnetic pulses, make the telephones and mobiles very handy. In power circuits, we use a device called relays, which has the potential to cut down a large current to the load, with the application of small amount of current. A small magnetic coil, which when energized, makes or brakes contact, thus doing a greater amount of work on the other end. Not to forget the usage of electromagnetism in medical field. Everyone must have heard of MRI scans. MRI- is the acronym for Magnetic Resonance Imaging. This sophisticated equipment can scan any minute details in the human body on the principle of electromagnetism.

Thus it is evident that the usage of electromagnetism is wide and everywhere. Everyday more and more equipments take birth in the market due to the development in the magnetism and electromagnetic studies.

This causes the bread to pop up.
