### Magnetic field

1. 1. MAGNETIC FIELD By : Agung Wahyu 09330089 5C
2. 2. MAGNETIC FIELD AROUND  ELECTRICAL CIRCUIT <ul><li>Magnetic field is a space where other magnet-magnet having a magnetic force </li></ul>What is the magnetic field ??
3. 3. MAGNETIC FIELD AROUND  STRAIGHT WIRE STREAMY <ul><li>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. </li></ul>A. DIRECTION OF MAGNETIC INDUCTION
4. 4. MAGNETIC FIELD AROUND  STRAIGHT WIRE STREAMY
5. 5. MAGNETIC FIELD ON SOLENOID
6. 6. 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 solenoid L  = length of solenoid in meters (m)
7. 7. MAGNETIC FIELD IN THE TOROIDAL
8. 8. 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 coil I = 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)
9. 9. 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)
