10 Uses of Bar Magnet

Bar magnets, also known as block magnets, have stable magnetic fields, simple shapes, and are easy to work with, and have a wide range of uses in daily life, education, industry, and creative fields. Here are 10 common uses for bar magnets.

Bar Magnet Application 1 - Sensors

Such as position sensors, Hall sensors, speed/revolution sensors, magnetic switches (reed switches), proximity sensors, etc. The bar magnet can be used as an excitation magnetic source to control circuit on/off or position recognition.

Bar Magnet Uses 2 - Educational Demonstration

Bar magnets are a classic tool for teaching physics, and are often used to demonstrate the basics of magnetic lines of force, magnetic poles repelling and attracting each other, and the direction of the geomagnetic field to help students understand the principles of magnetic fields.

Bar Magnet Use 3 - Magnetic Door Suction / Door Clasp

Bar magnets are often installed on door edges or cabinet doors and used as door suckers or door latches, utilizing magnetic force to automatically attach and close the door panels, improving convenience and preventing accidental opening.

Bar Magnet Use 4 - Tool Fixing

On tool racks, maintenance benches or walls, bar magnets can be used to hold metal tools such as screwdrivers and wrenches in place, making them easy to reach and less likely to be lost.

Bar Magnet Use 5 - Iron removal equipment

Such as dry or wet magnetic separators, conveyor belt iron removers, magnetic grids/bars in automatic material dispensing systems, ferromagnetic separation in environmental protection equipment, magnetic filters in liquid pipelines, bar magnets are used to separate metal impurities.

Bar Magnet Use 6 - Finding Metal Objects

Attracts small pieces of metal such as pins, keys, paper clips, etc. that fall out of carpets and crevices.

Bar Magnet Use 7 - Magnetic Adsorption Structure

In devices such as tablets, Bluetooth keyboards, TWS earphones, protective cases, game controllers, etc., bar magnets are used to achieve magnetic attraction combination, automatic positioning, or detachable connection.

Bar Magnet Use 8 - Making a Simple Compass

This is also very simple, prepare a bar magnet, a needle, a bowl of water, a small piece of Styrofoam, magnetize the needle, magnetize the needle fixed horizontally on the Styrofoam, stationary with a bar magnet with known poles (e.g., marked with N/S poles) close to the needle, the attracting end is the S pole, the repulsive end is the N pole.

Bar magnet Use 9 - Magnetic door curtain/curtains

Replace traditional hooks, easy to dismantle and clean (e.g. mosquito nets, screen curtains).

Bar Magnet Use 10 - Motor Systems

Commonly, there are linear motors, electric toothbrush vibration motors, balance car motors, electric toothbrush vibration motors, etc. The magnet material is generally neodymium iron boron.

In addition to those described above, there are many, many more applications for bar magnets, such as packaging, leather goods, handbags, toys, electrical appliances, computers, medical care and more.
