Answer:

There are two types of magnetic poles, called the north magnetic pole and south magnetic pole. North magnetic poles are those that are attracted toward the Earth's geographic north pole. Like poles repel and unlike poles attract.

❥ ❥ Answer :-

☆ The main 7 types of magnets.

  • Neodymium iron boron (NdFeB) :– Permanent magnet
  • Samarium cobalt (SmCo) :– Permanent magnet
  • Alnico :– Permanent magnet
  • Ceramic or ferrite magnets :– Permanent magnet
  • Temporary Magnets :– magnetized in the presence of a magnetic field.
  • Electromagnets :– created by running an electrical current through a coil with a metal core.
  • Superconductors :– made of wire coils of special metal alloys without a metal core.

The north pole (N) and the south pole (S) of a magnet are located at its end .

The different shapes of the magnets are :-

  • Bar magnet :- A magnet’s power is focused at the poles and lessens at the sides. Bar magnets are generally the weakest shape, because the poles have the smallest area.They are most common shape used in everyday life. Bar magnets are also used for demonstrations in the classroom.

  • Horseshoe Magnets :- Horseshoe magnets are just bar magnets bent in a U shape. The U shape makes the magnet stronger by pointing the poles in the same direction. It can be used to pick up metal objects of any size depending on the strength of the horseshoe magnet. For example, small horseshoes can collect paper clips while industrial-sized horseshoe magnets are used in construction and engineering to pick up large pieces of heavy metal. Horseshoe magnets are also used at the bottom of pendulums.

  • Disc Magnets :- Because of the wide, flat surface, disc magnets have a large pole area making them strong, effective magnets.Disc magnets are used every day in clothing, fashion accessories, and home decor. Sewing disc magnets into clothing is a great way to hold fabric together. Industrial-sized disc magnets are commonly used to pick up old cars at junkyards.

  • Sphere Magnets :- Sphere magnets are often sold as toys and novelty items. Sphere magnets make popular desk toys such as Rattlesnake Eggs. This shape can also be used to create bracelets and necklaces. Spherical magnets are also effective tools when demonstrating how some elements and molecules are structured if you use the spheres to represent atoms.

  • Ring Magnets :- Ring magnets are usually used in science experiments such as a demonstration of magnetic repulsion where the magnetic rings are threaded through a wooden pole . Ring magnets are also occasionally used in medicine. For example, some studies have shown that they neutralize Implantable cardioverter-defibrillators (ICD) if they malfunction. ICDs correct the heart’s rhythm with an electric shock if it becomes irregular. Sometimes the ICD malfunctions and can apply more shocks than are needed, which can be fatal for the patient unless a ring magnet is applied to the patient’s chest.

  • Cylinder Magnets :- Cylinder magnets are sometimes used in medicine. Unlike metal rods, magnetic rods can be lengthened noninvasively by remote control even after the rods have been placed in the patient’s spine. This eliminates the need for multiple surgeries to lengthen the rod during treatment.
