Magnetism of magnet is due to
Web19 aug. 2015 · $\begingroup$ Do a "current balance" experiment in which two wires repel each other due to their magnetic interaction. One wire can lift the other wire. So it does work. However, for a free (charged) particle moving in a magnetic field the magnetic force is always perpendicular to the velocity since $\vec{F}_B = q\vec{v} \times \vec{B}$. WebA magnet freely suspended in a vibration magnetometer makes 40 oscillations per minute at a place A and 20 oscillations per minute at a place B. If the horizontal component of earth's magnetic field at A is 36×10−6 T, then its value at B is. If the period of oscillation of freely suspended bar magnet in earth's horizontal field H is 4sec ...

WebFor current in coils and conductors , magnetic intensity H is defined as. H = B0/ 𝝁0 =nI. When a magnetic field is applied to material , the material gets magnetised. The actual magnetic field (B) inside the material is the sum of the applied magnetic field (B0) and the magnetic field due to magnetisation (M). Web17 dec. 2024 · Assetion The magnetism of magnet is due to the spin motion of electrons Reason Dipole moment of electron is smaller than that due to orbit motion around nucleus. A. Both assertin and reason are true and reason is the correct explanation of assertion B. Both assertion and reason are true but reason is not the correct explanation of assertion
WebPhysicists use a hand mnemonic known as the right-hand rule to help remember the direction of magnetic forces. To form the mnemonic, first make an L-shape with the thumb and first two fingers of your right hand. Then, point your middle finger perpendicular to your thumb and index finger, like this: The right-hand rule is based on the underlying ... Web12 sep. 2024 · We can use the Biot-Savart law to find the magnetic field due to a current. We first consider arbitrary segments on opposite sides of the loop to qualitatively show by the vector results that the net magnetic field direction is along the central axis from the loop.
WebThe magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges. Two objects containing charge with the same direction of … WebThe magnetic moment is a directional vector. There are two kinds of spin modes of electrons in atoms. In most matter, there are as many electrons with upward and downward spins, and the magnetic moments they produce will cancel each other out, and the entire atom is not magnetic to the outside. Only the atoms of a few matters have different ...
