Moving Charges

1. Oerested tentatively exhibited that the current conveying conductor produces attractive field around it.

2. Attractive FIELD: Magnetic field at a point is in this manner equivalent to the power following up on a unit charge when it is moving with unit speed in a heading opposite to attractive field.

3. LORENTZ FORCE: The power experienced by a charged molecule moving in space where both electric and attractive fields exists is called Lorentz power.

4. CYCLOTRON: It is a mechanical assembly which can give a vast speed to charged particles.

5. CURRENT SENSITIVITY: Current affectability of a galvanometer is characterized as the avoidance per unit current.

6. VOLTAGE SENSITIVITY: Voltage affectability of a galvanometer is characterized as the avoidance per unit voltage.

7. AMMETER: An ammeter is an instrument utilized for measuring huge current.A low resistance associated in parallel with a galvanometer is known as a shunt resistance or just shunt.

8. SOLENOID: A round and hollow loop of an expansive number of turns is known as a solenoid.

9. Attraction: The property of pulling in little bits of iron and steel was alluded to as attraction.

10. Attractive DIPOLE: Two attractive posts of equivalent and inverse polarities isolated by a little separation frames an attractive dipole

11. Attractive ELEMENTS OF THE EARTH: Those amounts which depict the attractive field of the earth at a specific place totally in size and additionally course are known as the attractive fields at that place.

12. Plunge ANGLE OR INCLINATION: Dip edge at a spot is characterized as the point between the bearing of the aggregate power of the Earths'magnetic field and an even line in attractive meridian.

13. Flat COMPONENT: The segment of the resultant power of the Earth's attractive field in the level heading is called its even segment and is signified by B H.

14. MAGNETISATION: Magnetization of material is characterized as attractive minute per unit volume of that material.

15. DIAMAGNETIC SUBSTANCES: The substances which are weakly charged in a heading inverse to that of polarizing field in which these are placedare called diamagnetic substances.

16. PARA MAGNETIC SUBSTANCES: The substances which are unreservedly charged toward the polarizing field in which these are set are called para magnetic substances.

17. FERROMAGNETIC SUBSTANCES: The substances which are unequivocally charged toward the polarizing field in which they are set are called ferromagnetic substances.

18. HYSTERESIS: Hysteresis is the marvel appeared by ferromagnetic substances where by the attractive field actuation (B) of the medium depends on the current charging field (H) as well as on the past condition of the substance.

19. Lasting MAGNET: Those substances which at room temperature hold their ferromagnetic property for long time are called changeless magnet.

20. ELECTROMAGNETS: An electromagnets is a brief solid magnet and is only a solenoid with its twisting on a delicate iron center which has high penetrability and low rententivity.
