Question
For each of the four drawings, draw the direction (left or right) of the induced current in the secondary coil. Also find the direction of the magnetic field produced by this induced current.
Station 1. The Transformer-the theory behind. A transformer consists of two separate coils of wire wrapped around an iron core. See figure below Note that the iron core serves to "funnel" the primary coil's magnetic field lines to the secondary coi Second Quarter: First Quarter: Primary current decreasing. Primary current increasing. B of Iron Core primary coil follows iron core Current in primary Secondary Primary Secondary Primary coil Fourth Quarter: Third Quarter: Primary current is increasing in the opposite Primary current decreasing. direction. Iron Core ron Core Primary Secondary Primary Secondary For each of the four drawings above, draw the direction (left or right) of the induced current in the secondary coil. Also find the direction of the magnetic field produced by this induced current.Explanation / Answer
1)
direction of induced current in the secondary is same as direction of current in primary(i.e towards right)
direction of magnetic field produced by the induced current towards up.
2)
direction of induced current in the secondary is opposite to the direction of current in primary(i.e towards left)
direction of magnetic field produced by the induced current towards down
3)
direction of induced current in the secondary is same as direction of current in primary(i.e towards left)
direction of magnetic field produced by the induced current towards down.
4)
direction of induced current in the secondary is opposite to the direction of current in primary(i.e towards right)
direction of magnetic field produced by the induced current towards up.
