एक चुम्बक को चार समान भागों में इस प्रकार विभाजित किया जाता है कि प्रत्येक छोटे भाग की लम्बाई एवं चौड़ाई, प्रारम्भिक मान की आधी हो जाती है तो प्रत्येक भाग का ध्रुव सामथ्र्य होगा
1 \(m/4\)
2 \(m/2\)
3 \(m/8\)
4 \(4m\)
Explanation:
प्रत्येक भाग के लिये \(m' = \frac{m}{2}\)

किसी चुम्बक के अक्षीय रेखा पर, उसके केन्द्र से दो बिन्दुओं की क्रमश: दूरी \(10\) सेमी और \( 20\) सेमी है । इन बिन्दुओं पर चुम्बकीय क्षेत्र की तीव्रता का अनुपात \(12.5 : 1\). हैै, तो चुम्बक की लम्बाई .....\(cm\) है
(a) The magnetism of the magnetic is due to the spin motion of electrons. Each electron in an atom is revolving in an orbit around the nucleus. The revolving electron is equivalent to a tiny loop of current. Therefore, it possesses some orbital magnetic dipole moment \(\vec{M}_{1}=\) current \(\times\) area of the loop. In addition to the orbital motion, every electron is assumed to have a spin motion around its axis. Therefore, another dipole magnetic moment called spin magnet \(\vec{M}_{s}\) is also associated with electron. The vector sum of \(\vec{M}_{l}\) and \(\vec{M}_{s}\) provides the net magnetic dipole moment \(\vec{M},\) to the atom. \(\vec{M}_{s}\) is much greater than \(\vec{M}_{l}\), hence magnetism of magnet is due to spin of electrons.
