Electromagnets in Everyday Life: From Healthcare to Transportation

What is an Electromagnet?

A magnet can pull some metals. An electromagnet is special. It is a magnet that uses power. When the power is on, it is a magnet. When the power is off, it is not a magnet. Electromagnets are in many things we use. Superconducting magnets are extra-powerful.

 Magnets in Hospitals

Doctors use big magnets. These big magnets help them see inside our bodies.

2.1 MRI Machines: Seeing Inside You

MRI machines use very strong magnets. These magnets are electromagnets. The magnets help make pictures. The pictures show our bones and insides. MRI is safe. NdFeB magnets help MRI machines work better. Many MRI machines use them. Siemens Healthineers and GE Healthcare make These MRI Systems.

• MRI machines are big.
• MRI machines use electromagnets.
• NdFeB magnets make MRI better.
• Our Magnet Grade selection helps pick the right magnet.

2.2 Tiny Magnets in Our Bodies

Doctors also use small magnets. Some people have pacemakers. Pacemakers help the heart. Some pacemakers use tiny electromagnets.  These help the pacemaker “listen” to the heart. Magnetic drug delivery uses tiny magnets, too and deliver medicine. NdFeB magnets are used because they are strong and small. We make custom magnets for these medical devices.

Magnetic resonance therapy

There are also magnetic therapy devices for pain.

 Magnets in Fast Trains and Cars

Magnets help trains go fast. Magnets even help cars!

3.1 Maglev Trains: Trains That Fly!

Maglev trains are super-fast. These trains “fly” above the track! They do not touch the track. Electromagnets make them float. NdFeB magnets help make this happen.  Shanghai Transrapid in China is a maglev train. It goes very fast. Japan is making a new maglev train. It will be even faster. Our high-quality NdFeB Magnets Factory makes magnets for these super trains.

3.2 Electric Cars: Moving with Magnets

Electric cars use electric motors. Many electric motors use NdFeB magnets. These magnets help the motor work better. Tesla and Nissan Leaf cars use these magnets. These magnets help save energy. Our Magnet Coating options make sure the magnets last a long time.

3.3 Hyperloop: The next step

There is even something called Hyperloop. it goes fast using magnetic propulsion. Virgin Hyperloop has been tested at fast seeds, and uses less energy than regular trains because of magnetic levitation.

Why NdFeB Magnets are the Best

NdFeB magnets are very good for electromagnets.

4.1 Why We Like NdFeB

• They are super strong.
• They work in hot and cold.
• They are a good price.
• They last a long time.
• It’s good in renewable energy systems.

They are better than other magnets. Linear Induction motors use these.

4.2 When to Use NdFeB

Use NdFeB magnets when you need:

• Strong magnets.
• Magnets that last.
• Magnets for MRI.
• Magnets for wind turbines.
• We make magnetic resonance imaging magnets.
• We also make electromagnetic flow meter magnets.

Buying the Right NdFeB Magnets

It is important to pick the right magnet.

5.1 Things to Think About

• Grade: N35, N42, N52… (stronger number is stronger).
• Coating: Nickel or epoxy coating.
• Hot or Cold: Pick a magnet that works at the right temperature. Consider using magnetic particle imaging in design.

  5.2 Magnets for Different Jobs

  Different jobs use different magnetic field applications.
• Hospitals: Magnets must be safe for people.
• Trains and Cars: Magnets must be strong and not break.
• Quantum computing magnets need to be accurate.
