Explain the method of plotting magnetic field lines by using a …
The method explained below shows the plotting of magnetic field lines with the help of a small compass needle: Procedure: 1. With the help of some board pins, fix a sheet of paper on a …
What will happen to a compass needle when the compass is …
The direction of magnetic field at a point directly above the wire is from south to north. Thus, when a magnetic compass is brought below the current carrying wire the compass needle show …
When the current us swtiched on through a wire, a compass …
Question 6 When the current is switched on through a wire, a compass needle kept nearby gets deflected from its north-south position. Explain.
When current passes through the circuit a compass needle rests
The earth acts like a huge magnet. Thus in the absence of electric current a compass needle always comes to rest in Earths North-south direction. However, when current passes through …
Briefly explain an activity to plot the magnetic field lines around a ...
5. Again mark the position of the other end (N-pole) of the compass needle. 6. Repeat the steps 4 and 5, till you reach the other end (S-pole) of the bar magnet. 7. Join all the points with a sharp …
A compass needle, which shows the direction the earth's ... - Toppr
A compass needle free to turn in a horizontal plane is placed at the centre of a circular coil of 30 turns and radius 12 cm. The coil is in a vertical plane making an angle of 450 with the …
Why does a compass always point to the north? - Toppr
The needle of a compass is a magnet. The needle is suspended on a sharp point to minimize the effect of friction such that the weak magnetic field of the Earth can cause the north-seeking …
Why does a magnetic compass needle pointing North and South …
Thus, when a magnetic compass that is pointing in the north-south direction according to the earth's magnetic field, shows deflection with respect to the strength of the magnetic field that is …
What change in the deflection of the compass needle placed a
What change in the deflection of the compass needle placed at a point near current carrying straight conductor shall be observed if the (a) current through the conductor is increased? (b) …
A magnetic compass is placed inside a solenoid and the needle is ...
A magnetic compass is placed inside a solenoid and the needle is pointing in the direction as shown : a) complete the diagram by drawing arrow heads to indicate the direction of current …
