Definition
Straight CCC
we can see that a straight CCC forms a M.F. in the form of concentric circle where the centre is the conductor.
Right Hand Thumb Rule
This rule is used to find the direction of current or the direction of magnetic field of aStraight CCC.
Circular Loop
The circular loop forms M.F like this
It makes a straight line in the middle. And it makes two different poles in two different sides (like two sides of the same coin)
Connection between Direction of current and Polar Face
Solenoid
A solenoid is a coil made of circular loops which has a magnetic field similar to that of a bar magnet.
Points to be noted
- M.F is the same inside all the points of a solenoid.
- A soft iron (Fe) can be used as a core to convert it into a electromagnet.
