How do you calculate the magnetic dipole moment of a bar magnet?

∙ 10y ago
The strength of a magnet can be determined by measuring its flux density (B) which is expressed in teslas. The flux density will vary according to where relative to the magnet it is being measured. The instrument for doing this is a flux-density meter (which was called a 'gaussmeter' - 'gauss' being an obsolete unit of measurement for flux density, from the cgsA metric system).

∙ 10y agoThe magnetic dipole moment of a bar magnet is the point at which there is a neutral magnetic field. This is calculated only after comparing the relative strength of the positive and negative ends of the magnet.

What is difference between between electric dipole moment and magnetic dipole moment?
Magnetic dipole is due to two poles of magnet. Electric dipole is due to +ve and -ve charges of electric charges.
What is magnetic moment?
Language plays sometimes a dominant role even in understanding scientific concepts.Magnetic dipole moment and Moment of a magnet, they differ because of the size of the magnetic material. Magnetic dipole is the one with opponent poles but separated by a very smalldistance. But, in case of a long bar magnet, the distance of separation of poles would be larger. In such cases, we calculate the moment of the magnet.Moment of the magnet is equal to the product of the pole strength and the distance between the opposite poles.Dipole magnetic moment is also the same. But in case of dipole formed due to circulation of electron, its dipole moment is got by the product of current and area of loop made by the electron circulation.
What are Magnetic Properties of Metals?
Iron (Fe) Cobalt (Co) and Nickel (Ni) iron, steel, nickel, and cobalt all have magnetic properties. Lodestone is also magnetic and was used to make early compasses a long time ago because it has magnetic metal elements in it.
Why is magnitude of an electron spin greater than its magnetic moment?
The Spin magnetic moment i approximately the same as the angular magnetic dipole moment. What then do you men by grater magnitude?
What creates a magnetic field?
Both magnetic materials and moving electric charges induce magnetic fields. "A magnetic field can be created with moving charges, such as a current-carrying wire. A magnetic field can also be created by the spin magnetic dipole moment, and by the orbital magnetic dipole moment of an electron within an atom." A magnetic field can be produced by either a permanent magnet, or an electromagnet, the latter requiring suitable energization to function.
What is the potential energy of a point magnetic dipole of moment M placed in a uniform magnetic field B?
lU=-mB Metal
For a loop of current carrying wire in a uniform magnetic field the potential energy is a minimum if the magnetic dipole moment of the loop is?
in the same direction as the field
Does CH3NH2 have a dipole moment?
NH3 is not symmetrical.So it has a dipole moment
Does ammonia have a dipole moment?
NH3 is an asymmetrical compound.So it is exhibits.
What is the dipole moment of glucose?
The dipole moment of Glucose is 1.8
What is the dipole moment of SiH4?
no dipole moment
Why four magnetic materials are strongly attracted to the magnet?
Four common magnetic materials that are strongly attracted to a magnet are iron, nickel, cobalt, and certain alloys of these metals. This is because these materials have unpaired electrons in their atomic or molecular structure, which creates a magnetic moment. When a magnet is nearby, the magnetic field of the magnet aligns the magnetic moments of these materials, causing them to be strongly attracted to the magnet.
