Magnetic field, current, loop, and Biot-Savart Law are four entities closely related to the magnetic field in a current loop. The magnetic field produced by a current loop is directly proportional to the current flowing through the loop and inversely proportional to the square of the distance from the loop. The direction of the magnetic field can be determined using the right-hand rule, which states that if you point your right thumb in the direction of the current, your fingers will curl in the direction of the magnetic field. The Biot-Savart Law provides a mathematical equation that can be used to calculate the magnetic field at any point in space due to a current loop.

What’s the deal with this formula?
It says that the total magnetic field around a current loop is equal to the permeability of free space times the current flowing through the loop. In other words, the more current you have, the stronger the magnetic field.
How to Use It
To find the magnetic field created by a loop, you need to do some math. Imagine you have a loop in the shape of a circle. You can break the loop up into lots of tiny segments, called dl. Then, you calculate the magnetic field created by each segment and add them all up.

Imagine trains gliding effortlessly over tracks, floating on a cushion of magnetic fields. No wheels, no friction, just smooth, silent, and lightning-fast travel. Maglev trains use electromagnets to create a magnetic field that repels the track, lifting the train up to a few centimeters off the ground.
The secret behind maglev’s magical powers lies in the Meissner effect, which makes superconductors (materials that conduct electricity without any resistance) behave like diamagnetic materials. When superconductors are cooled to very low temperatures, they expel magnetic fields, creating a force that pushes the train upwards.
Some maglev trains use electrodynamic suspension (EDS), where superconductors line the track and repel the superconducting magnets on the train. Others use electromagnetic suspension (EMS), where magnets on the train attract the ferromagnetic track below, levitating the train.
Maglev trains offer plenty of perks. They’re wicked fast, reaching speeds of over 500 kilometers per hour (311 miles per hour). They’re also smooth and quiet, making the journey an absolute joy. Plus, they’re efficient thanks to the lack of friction, reducing energy consumption.
One of the most exciting aspects of maglev trains is their potential for sustainable transportation. They don’t release any emissions, making them an eco-friendly option. And their efficiency means they use less energy, further reducing their environmental impact.
