# Magnetic Levitation Calculator

### Introduction

Magnetic levitation, or maglev, is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract gravitational pull and any other forces. This technology is widely used in applications like maglev trains and certain types of bearings. This article introduces a magnetic levitation calculator to help you understand the dynamics of maglev systems.

### How to Use

To use the magnetic levitation calculator, you need to input the necessary parameters such as the magnetic field strength, the distance between magnets, and the weight of the object. Once you input these values, click on the “Calculate” button to get the result.

### Formula

The formula to calculate the magnetic force required for levitation is derived from the balance of forces acting on the levitated object. The key formula used is:

Where:

- F is the magnetic force.
- μ0 is the permeability of free space (4π×10−7 Tm/A
- M1 and M2 are the magnetic moments of the two magnets.
- d is the distance between the two magnets.

### Example Solve

Let’s consider an example where we have the following parameters:

- Magnetic moment of magnet 1 (M1): 1.2 A⋅m2
- Magnetic moment of magnet 2 (M2): 1.5 A⋅m2
- Distance between the magnets (d): 0.05 m

Using the formula, we can calculate the force as follows:
