Magnetic moment of circular coil
WebSolution: The magnetic moment is a measure of the strength of a magnetic source. The equation for magnetic moment in the current carrying loop, carrying current I and of area vector A for which the magnitude is given by M = I A where I is current A, is area (= πr2) ∴ M = I πr2 ⇒ M ∝ r2 WebMagnetic Induction 3D Rotating coil AC Generator 3D Alternating Current Root-Mean-Squared Current (Sinusoidal) Root-Mean-Squared Rectified Current AC Transformer AC Power Root mean square Quantum Physics Photoelectric Effect Photoelectric effect Energy Level Diagrams Hydrogen Atom Electron Energy Levels Nuclear Physics Half-Life Action!!!
Magnetic moment of circular coil

WebFigure 3a shows a length of wire carrying a current i and bent into a circular coil of one turn. In Fig. 3b the same length of wire has been bent to give a coil of two turns, ... The … WebThe magnetic moment of a circular coil carrying current isa)directly p... Answer is c) Magnetic Moment is: M = NiA => M is directly proportional to A => M is directly proportional to r^2 (As l=2πr => l is directly proportional to r) So, M is directly proportional to l^2 where, l is the length of wire in the coil.
