What is the maximum magnetic field strength for a given size permanent magnet?

In summary, magnetic field strength is a measure of the intensity or force of a magnetic field and is represented by the symbol B. It can be calculated using the formula B = μ0 * H or by measuring the force exerted on a test particle. Factors such as distance, size, and materials can affect magnetic field strength, and it is typically measured using a magnetometer. This measurement is commonly expressed in units of tesla or gauss, but other units may also be used. Magnetic field strength plays a crucial role in various scientific and technological fields, such as physics, engineering, and medicine, and is used in applications like magnetic levitation, MRI machines, and compasses.

Now I'm sure one can find this at google somehow , even though I wasn't that successful with it.

Does someone know what is the highest magnetic field strength for a givem size permanent magnet for example?
Like a 1cm ball of neodymium or some other material, what would be the highest field strength possible to achieve for a given material of a given size?

For permanent magnets, the limit is given by the saturation, and it does not depend on the size of the magnet. ~2T are possible, everything beyond that needs coils, lasers or other stuff.

1. What is a magnetic field strength?

A magnetic field strength is a measure of the intensity or force of a magnetic field. It is typically represented by the symbol B and is measured in units of tesla (T) or gauss (G).

2. How is magnetic field strength calculated?

Magnetic field strength can be calculated using the formula B = μ0 * H, where μ0 is the permeability of free space and H is the magnetic field intensity. It can also be calculated by measuring the force exerted on a test particle placed in the field.

3. What factors affect magnetic field strength?

The strength of a magnetic field can be affected by the distance from the source of the field, the size and strength of the magnetic source, and the material the field is passing through. It can also be affected by the orientation and movement of the source or the test particle.

4. How is magnetic field strength measured?

Magnetic field strength can be measured using a magnetometer, which detects changes in the magnetic field. The unit of measurement for magnetic field strength is typically the tesla or gauss, but other units such as ampere per meter (A/m) or oersted (Oe) may also be used.

5. Why is magnetic field strength important?

Magnetic field strength is important in various fields of science and technology, including physics, engineering, and medicine. It is crucial for understanding and manipulating electromagnetic phenomena and is used in applications such as magnetic levitation, MRI machines, and compasses.
