WebI dont know the about solenoid but in case of ring/coil the magnetic field is given by B= ɥ/4⫪ 2i (A)/ (r²+d²)^3/2 where A=⫪r². equating this will give you the answer if you take d>>r it will become easy. ans will be M=ɥ/4⫪ 2i (A1) (A2)/d³ or M=ɥ/4⫪ 2i.⫪ (R1)².⫪ (R2)²/d³ I hope that helps... Comment ( 3 votes) Upvote Downvote Flag Video transcript WebOVERVIEW. A Voice Coil is a type of solenoid linear actuator within which an electrical coil and a permanent magnet interact to create high speed, precisely controlled linear motion. The term Voice Coil is derived from the fact that this type of electromagnetic device is used in audio speaker technology to rapidly move the cone of the speaker ...

A solenoid is generally easy to wind, and near its center, its magnetic field is quite uniform … WebA solenoid is a device that controls the flow of electricity. It is a kind of electromagnet that creates a regulated magnetic field and is made out of a helix coil of wire with a length significantly longer than its diameter. The mutual inductance of two co-axial solenoids is calculated as: M = 0n1n2A2l. エスクロー 基本情報
