What Suits The Best Example To Explain Magnetic Effect Of Electric Current?


Answer. (b) The electric effects of moving magnet :- The best example is generator.



What are the consequences if magnetic effect can not caused by the electric current?

Answer. The magnetic field disappears when the current is turned off. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet.


What will be the effect on the magnetic field of electric current flowing through the electric circuit is increased?

Current is directly proportional to magnetic force for a straight current carrying conductor in a uniform magnetic field. So the force is directly proportional to the size of the current. Practically this means the following: If the current is increased by five times the force will also increase by five times.


What uses magnetic effect of electricity?

Answer. ELECTRIC BELL uses the magnetic effects of electricity.


Where magnetic effect of current is used?

Magnetic effect of current is used – Electric bell, Cranes to lift magnetic material.


What is magnetic effect of electric current how it is useful for us give any two example of devices in which this effect is used explain how electromagnet is important for us?

Appliances like the electric bulb, fan, television, refrigerator, washing machine, motor, radio, everything works due to electricity. When electric current passes through current carrying conductor or coil then a magnetic field is produced around it.


Does magnetism affect chemical reactions?

According to quantum mechanics, chemical reaction depends on electron spin. The spin of unpaired electrons involved in the chemical reaction can be influenced by a magnetic field, thus changing the entropy of the reaction system.


What will happen if the number of electric cells is increased on the magnetic needle?

Answer: Increase 'in the number of cells will further increase the deflection in magnetic compass.


What are the factors affecting the strength of an electromagnet?

The four main factors that affect the strength of an electromagnet are the loop count, the current, the wire size, and the presence of an iron core.


What is meant by the magnetic effect of current?

The term 'magnetic effect of electric current' means that an electric current flowing in a wire produces a magnetic field around it. An iron, steel, nickel and cobalt.


What suits the best example to explain magnetic effect of electric current?

Answer. (b) The electric effects of moving magnet :- The best example is generator.


What is dimension in physics for class 11?

Dimensions of any physical quantity are those powers which are raised on fundamental units to express its unit. The expression which shows how and which of the base quantities represent the dimensions of a physical quantity, is called the dimensional formula.
