A promotional magnet is a material or object that produces a magnetic field. A “hard” or “permanent” magnet is one which stays magnetized for a long time, such as magnets often used in refrigerator doors. A “soft” or “impermanent” magnet is one which loses its memory of previous magnetizations. “Soft” magnetic materials are often used in electromagnets to enhance (often hundreds or thousands of times) the magnetic field of a wire that carries an electrical current and is wrapped around the magnet; the field of the “soft” magnet increases with the current. Permanent magnets occur naturally in some rocks, particularly lodestone, but are now more commonly manufactured. A magnet’s magnetism decreases when it is heated and increases when it is cooled.

From baseball bats to golf shoes, packing all such accessories as well as golf equipment for your much awaited golf vacations can truly be a nightmare. A better option would be to borrow golf or basketball equipment from the loan sports club.
