fleming's left hand rule class 10

Here is the explanation of Fleming's left hand rule class 10 science and also Fleming's right hand rule science class 10 and all the topics of magnetic effect of electric current class 10.here you also find the notes on physics chemistry math for class 9th and 10th and 11th and 12th science. all the topics are explained in detail in easy language as a student can understand it and make the exam perfect.

Specially these notes are for those students who prepared for their board exam for class 10th and 9th 12th respectively. Because all the topic covered can be explained in full detail and easy language as far as possible.

Fleming's left hand rule:-

According to Fleming's left hand rule first finger shows the direction of magnetic magnetic field,Central figure shows the direction of electric current flowing in the conductor and the thumb shows the direction of force.

Fleming's right hand rule:-

According to Fleming's right hand rule first finger soch the direction of electric field, Central finger shows the direction of induced current in the conductor and the thumbs shows the direction of motion of conductor in magnetic field.

Solenoid:-

It is a wire wrapped closely in the form of a helix.
It is a conducting wire of spiral shape when electricity is passed through the wire it produces magnetic field, the direction of which is directed by using the maxwell's right hand cross screw rule.
The current kich anticlockwise direction at. 'A' North pole is produced and at the end 'B' a south police produced.

Magnetic field inside the solenoid

The strength of magnetic field increase if the current flowing in the solenoid increases and vice versa.

If number of turns per unit length is increases then magnetic field also increases.

Toroid:-

A circular solenoid is called toroid.is a solenoid is banned in a circular shape and the end are joint we get a toroid.

Define of ampere:-

If two parallel long wires kept 1 metre apart income carry equal current in the same direction and there is a force of 2 x 10 to the power minus 7 Newton attraction of each wire the current in each wire is said to be one ampere.

Electromagnetic induction:-

it is the phenomenon of producing induced current in a closed circuit or coil due to the change in position of magnetic field in the nearby circuit or a closed coil.

Factor on which induced current depends:-

Induced current is directly proportional to number of turns of the coil it means that if a coil has a large number of turns then large induced current is produced in the closed coil.
Induced current is directly proportional to strength of magnet.
induced current directly proportional to speed of the coil it means that if the magnet moves very quickly than large induced current is produced in the closed coil.

Domestic electric circuit:-

The electric power is supplied to the house of factories through underground cable for overhead wire on poles.
Overhead aur Keval known as phase wire, live wire, neutral wire and Earth wire.
Difference between the live wire and neutral wire each 220 volt.
Live wire is covered with insulation of red and brown colour.
Neutral wire with an insulation of black and blue colour and the earth wire is covered with insulation of green or yellow colour.

Electric fuse:-

It is a Safety device used to save the electrical appliances like electric bulb, electrical tube TV etc. From burning when large amount of current flow in a circuit.
It is a wire made of copper-aluminium tin-lead alloy.
It has low melting point.
it is connected in series with an electrical device like bulb, TV, refrigerator, washing machine etc.
the capacity of a phase wire is a large if it is thick and capacity of the fuse wire is small if it is thin.
short circuiting takes place when the live wire and neutral wire come in direct contact.
overloading means law of large amount of current in the circuit beyond the pammicable value of current.
Aur another word when many electrical appliances of high power rating are connected in a single circuit then overloading occur.
