To calculate the magnetic field strength of a stack of magnets, you can use the formula B = µ0 * (m1 + m2 + ... + mn) / (2πr), where B is the magnetic field strength, µ0 is the permeability of free space, m1-mn are the magnetic moments of each individual magnet, and...

Magnetic Field Strength The strength of an electric field is defined in terms of the force that is exerted on a charged particle in that field. We use the same procedure for defining the strength of a magnetic field. But there is an important difference between the two cases. A stationary ...
The magnetic field strength of magnet can be measured by Gauss Meter, or Tesla Meter. Now, many magnet users have their own Gauss Meter, and also establish the acceptance criteria of magnetic field strength. For multi-polar magnet, the magnetic field strength will be measured by Magnet Analyzer...
An analytical expression is obtained for the magnetic strength of a permanent magnet in the form of a rectangular parallelepiped uniformly magnetized at an angle to its lateral faces. The results from experimental measurements of the magnetic field strength of a permanent magnet in the form of a ...
where θ is the angle between the directions of v and B. This force is often called the Lorentz force. In fact, this is how we define the magnetic field strength B—in terms of the force on a charged particle moving in a magnetic field. The SI unit for magnetic fi...

What is the SI unit for the strength of a magnetic field? What is a changing magnetic field? Where is the strength of a magnetic field the weakest? Where is the magnetic field of a magnet strongest? What is induced magnetism? What can produce magnetic fields?
In this installment, we're going to focus on questions about measuring the field strength of a magnet. Perhaps the most common question is: I'm measuring theSurface Fieldof a specific magnet with magnetometer, and I'm measuring less than the specifiedSurface Field. Why are my readings low?
