Magnetic forces are fundamental interactions that occur between magnetic fields and magnetized objects. They play a crucial role in various phenomena, ranging from everyday experiences to complex scientific applications.

From the humble magnetic compass to the powerful Magnetic Particle Imaging (MPI) machines used in medical diagnostics, magnetic force plays an essential role in countless applications.

In this exclusive article, we will explore some of the most captivating examples of magnetic force that we see in our day-to-day life. So without wasting any more time, let’s dive right in…!!!

Examples of Magnetic Force in Daily Life

  • Magnetic Compass
  • Magnetic Storage Device
  • Magnetic Particle Imaging
  • Magnetic Stirrer
  • Magnetic Levitation
  • Magnetic Separation

The very first one in my list of 6 magnetic force examples in everyday life is the magnetic compass. In fact, it’s one of the earliest applications of magnetism. A magnetic compass is a simple and widely used navigation tool that utilizes the Earth’s magnetic field to determine directions.

It basically revolutionized the idea of a navigation system by allowing sailors to determine their direction in an open ocean. It consists of a magnetized needle mounted on a pivot so that it can rotate freely.

By aligning itself with Earth’s magnetic field, the compass needle always points toward the magnetic North Pole allowing sailors to find out their cardinal direction.

Magnetic Storage Device

A magnetic storage device or magnetic storage medium is a type of data storage device like hard drives and magnetic tapes that uses magnetized materials to store and retrieve digital information. For decades, it has been a fundamental technology in the field of data storage.

In fact, it is still widely used in today’s world and is commonly dubbed as the backbone of digital data storage. They basically use magnetic fields to encode and retrieve information, allowing us to store vast amounts of data.

Magnetic Particle Imaging

Magnetic Particle Imaging (MPI) is the fastest-emerging medical imaging technique that enables high-resolution and real-time visualization of the distribution of superparamagnetic iron oxide nanoparticles (SPIONs) in biological tissues.

It basically utilizes powerful magnetic fields and radio waves to visualize the internal structures of the body. In fact, it offers several advantages over traditional imaging modalities, such as magnetic resonance imaging (MRI) and computed tomography (CT) for early disease detection and monitoring.

Magnetic Stirrers

Magnetic stirrers are commonly used laboratory devices that employ a rotating magnetic field to stir and mix liquids or solutions without the need for physical contact.

It consists of a magnetic stir bar, a small magnetic rod, and a motorized base unit that generates the rotating magnetic field. This efficient and contamination-free method finds applications in various scientific disciplines.

Magnetic Levitation

Magnetic levitation or Maglev is a fascinating futuristic transportation phenomenon that involves using magnetic forces to suspend and propel trains without any physical contact or friction.

When two magnets with like poles are brought close to each other, they repel each other by creating a force that opposes their contact. Therefore, by eliminating physical contact, maglev trains achieve incredible speed enabling high-speed transportation.

Magnetic Separation

Last but not least one in my list of top 6 magnetic force examples in real life is the use of magnetic separation devices. As the name suggests, it is a valuable technique used in recycling and mining industries to separate or extract magnetic materials from non-magnetic ones.

Some Other Magnetic Force Examples in Daily Life

Apart from the above-mentioned ones, I am also mentioning a few here.

  • Electric Motor
  • Magnetic Resonance Imaging (MRI)
  • Maglocks and Magnetic Latches
  • Electromagnetic Induction
  • Maglev Roller Coasters
  • Magnetic Bearings
  • Biomagnetic Separation, etc.

I am a mechanical engineer by profession. Just because of my love for fundamental physics, I switched my career, and therefore I did my postgraduate degree in physics. Right now I am a loner (as ever) and a Physics blogger too. My sole future goal is to do a Ph.D. in theoretical physics, especially in the field of cosmology. Because in my view, every aspect of physics comes within the range of cosmology. And I love traveling, especially the Sole one.
