Magnetic length is related to the larmour radius: r = mv/(qB) = mvr/(qBr)=L/(qBr)
Since L is quantised as m(l)h; m(l) =magnetic quantum number= integers, so let it be unity for the smallest value or r, then r^2=h/(qB) and the vale of r with m(l) = 1 is called magnetic length l(B): so l(B) = sqrt(h/qB)
The physical interpretation of this length is that the area swept out by this length (2*pi*l*l) contains one quantum of magnetic flux.

What is the relation between geometric length and magnetic length of a magnet?
The geometric length of a magnet is the physical size of the magnet, while the magnetic length refers to the region of influence where the magnetic field is produced by the magnet. The two lengths are related in that the magnetic length typically extends beyond the geometric length due to the nature of magnetic fields.
Can effective magnetic moment be calculated from negative mass magnetic susceptibility ie diamagnetic substances?
Yes, the effective magnetic moment for a diamagnetic substance can be calculated using its negative mass magnetic susceptibility. This can be achieved by applying the formula for effective magnetic moment: μ = (χm - 1) * V, where χm is the magnetic susceptibility and V is the volume of the substance. The negative sign of the susceptibility reflects the opposing magnetic response of diamagnetic materials.
What is the significance of magnetic length in the context of electromagnetic fields?
The magnetic length is a measure of how far a magnetic field can extend before its strength decreases significantly. In the context of electromagnetic fields, it helps determine the range and effectiveness of magnetic forces, influencing the behavior of charged particles and the overall dynamics of electromagnetic interactions.
How can you find effective length of a simple pendulum?
The effective length of a simple pendulum can be found by measuring the distance from the point of suspension to the center of mass of the pendulum bob. This effective length can be used to calculate the period of the pendulum using the formula T = 2π√(L/g), where T is the period, L is the effective length, and g is the acceleration due to gravity.
What is the magnetic field equation for a solenoid and how does it relate to the behavior of the magnetic field within the solenoid?
The magnetic field equation for a solenoid is given by B nI, where B is the magnetic field strength, is the permeability of free space, n is the number of turns per unit length, and I is the current flowing through the solenoid. This equation shows that the magnetic field strength inside a solenoid is directly proportional to the current flowing through it and the number of turns per unit length. As a result, increasing the current or the number of turns per unit length will increase the magnetic field strength within the solenoid.
What is the magnetic length of a magnet?
The effective length of a magnet is the distance between the magnetic poles. It is always less than the geometric length of the magnet,though the actual relation between the two depends on the shape of the magnet.
Why magnetic length is taken as 2L?
The magnetic length is defined as 2L because it represents the effective length of a magnetic dipole, where L is the distance from the center of the dipole to each pole. This doubling accounts for both poles of the dipole, as the magnetic field generated is influenced by the entire length of the dipole, not just one end. Hence, the factor of 2 ensures that the full extent of the dipole's influence is considered in calculations and analyses of magnetic fields.
What is geometric length in magnets?
Geometric length in magnets refers to the physical dimensions of the magnet, such as its length, width, and thickness. This measurement is important in determining the overall size and shape of the magnet, which can impact its magnetic properties and behavior.
What is the relation between geometric length and magnetic length of a magnet?
The geometric length of a magnet is the physical size of the magnet, while the magnetic length refers to the region of influence where the magnetic field is produced by the magnet. The two lengths are related in that the magnetic length typically extends beyond the geometric length due to the nature of magnetic fields.
Why magnetic lentgh is less than geometric length of magnet?
The magnetic length is shorter than the geometric length of a magnet because the magnetic field extends beyond the physical boundaries of the magnet. The field lines curve and loop around the magnet, causing the magnetic effect to reach out further than the physical dimensions of the magnet itself.
Why is the magnetic length of a bar magnet less than the actual physical length of it?
The magnetic length of a bar magnet is less than its physical length because the magnetic field around the magnet extends outward from the poles, so only a portion of the magnet's length corresponds to the region where the magnetic field is strongest. The magnetic field weakens as you move away from the poles, so the effective length of the magnet for magnetic interactions is shorter than its physical length.
Can effective magnetic moment be calculated from negative mass magnetic susceptibility ie diamagnetic substances?
Yes, the effective magnetic moment for a diamagnetic substance can be calculated using its negative mass magnetic susceptibility. This can be achieved by applying the formula for effective magnetic moment: μ = (χm - 1) * V, where χm is the magnetic susceptibility and V is the volume of the substance. The negative sign of the susceptibility reflects the opposing magnetic response of diamagnetic materials.
How effective is magnetic jewelry?
If by effective you mean if it stays on or not, it depends on how strong of a magnet it is, however I believe it to be as effective as it was made to be.
What is the average size of magnetic tape?
Magnetic tapes are usually used for data storage. The length of a magnetic tape is 10.5 inches
How is the day length determined on Saturn?
From changes in its magnetic field, assuming that the magnetic field rotates with the core.
What is the average size of a magnetic tape?
Magnetic tapes are usually used for data storage. The length of a magnetic tape is 10.5 inches
Define effective length of a column.?
The equations for critical buckling load include the variable KL which is the effective length. K is the effective length factor. Values for K vary depending on the load and type of supports of a member.NOTE:The larger the effective length, the less strength there is in a column. So, if there is a choice of effective lengths, the larger value will give the more conservative strength value.
