MAGNETIC FIELD AROUND ELECTRICAL CIRCUIT

Magnetic field is a space where other magnet-magnet having a magnetic force

What is the magnetic field ??

MAGNETIC FIELD AROUND STRAIGHT WIRE STREAMY

Grasp the wire straight with your right hand to the thumb indicates the direction of strongcurrents, the direction of rotation of the fourth finger would reveal who sealed the circledirection of magnetic field lines.

A. DIRECTION OF MAGNETIC INDUCTION

MAGNETIC FIELD AROUND STRAIGHT WIRE STREAMY

MAGNETIC FIELD ON SOLENOID

MAGNETIC FIELD ON SOLENOID

Magnitude of the magnetic field disumbu center (point O) The solenoid can be calculated

Bo = magnetic field in the central solenoid in tesla (T)

μ0 = permeability of free space = 4п. 10 -7 Wb / amp. M

I = strong electric current in amperes (A)N  = number of windings in the solenoidL  = length of solenoid in meters (m)

MAGNETIC FIELD IN THE TOROIDAL

MAGNETIC FIELD IN THE TOROIDAL

Magnitude of the magnetic field in the middle of the toroid (at points which are on the redcircle) can be calculated

Bo = Meda dititik magnet in the middle of the toroid in tesla (T)

N = number of windings on the solenoid coilI = strong electric current in amperes (A)a = the average jari2 inner and outer radius

of the toroid with units of meters (m)a = ½ (R1 + R2)

LORENTZ FORCE

Thumb : shows the direction of the Lorentz force (FL) Direction of the Lorentz force

Index finger: indicates the direction of the magnetic field (B)

Middle finger: indicates the direction of electric current (I)
