give me important questions for magnetic effects of electric current , class 10
Answers
2.Thumb rule, maxwell corkscrew rule
3.Magnetic field due to current through a circular loop(imp)
4.Fleming's rule
5 electric motor and electric generator
6. Electromagnetic induction
A magnetic field is a force field that is created by magnetic dipoles and moving electric charges, and it exerts a force on other nearby moving charges and magnetic dipoles. If a magnetic compass is brought near a electrically charged conductor then the needle of this compass gets deflected because of the flow of electricity.
1.Describe an activity to show that the magnetic field lines produced when current is passed through the circular coil.
2. What is meant by solenoid? How does a current carrying solenoid behave? Give its main use.
3.For the current carrying solenoid as shown below, draw magnetic field lines and giving reason explain that out of the three points A, B and C at which point the field strength is maximum and at which point it is minimum.
4. With the help of a diagram of experimental setup describe an activity to show that the force acting on a current carrying conductor placed in a magnetic field increases with increase in field strength
5.What are magnetic field lines? Justify the following statements
(a) Two magnetic field lines never intersect each other.
(b) Magnetic field lines are closed curves.
7.Why and when does a current carrying conductor kept in a magnetic field experience force? List the factors on which direction of this force depends?
