Answer 1

• Fix a sheet of white paper on a drawing board using some adhesive material.
• Place a bar magnet in the centre of it.
• Sprinkle some iron filings uniformly around the bar magnet (Fig. 2). A salt-sprinkler may be used for this purpose.
• Now tap the board gently.
• What do you observe?

The iron filings arrange themselves in a pattern as shown Fig. 2. Why do the iron filings arrange in such a pattern? What does this pattern demonstrate? The magnet exerts its influence in the region surrounding it. Therefore the iron filings experience a force. The force thus exerted makes iron filings to arrange in a pattern. The region surrounding a magnet, in which the force of the magnet can be detected, is said to have a magnetic field. The lines along which the iron filings align themselves represent magnetic field lines.Are there other ways of obtaining magnetic field lines around a bar magnet? Yes, you can yourself draw the field lines of a bar magnet.

⠀

$\large\bf\underline\blue{Introduction}$

we know that a compass needle gets deflected when the current flows in a nearby wire. This is similar to the observation when we bring a magnet close to it. When we connect these two observations, we can conclude that the current flows through a wire, the wire behaves like a magnet. This is the magnetic effect of current. In fact an electric current can be used to make a magnet.

⠀

$\large\bf\underline\purple{Aim}$

To study the magnetic effect of electric current.

⠀

$\large\bf\underline\blue{Materials~Required}$

• Battery
• Copper wire
• Compass needle
• Table

⠀

$\large\bf\underline\pink{Theory}$

A conductor carrying current is always associated with a magnetic field around it. This is called the magnetic effect of current. It was first discovered by H.C. Oersted in 1820.

⠀

$\large\bf\underline\orange{Procedure}$

1. Fix a copper wire on the table.
2. Connect two ends of wire with a battery.
3. Place a compass needle near the wire.
4. Change the position of compass needle on the table.
5. Needle in compass shows the deflection.

⠀

$\large\bf\underline\red{Observation}$

when a circuit is disconnected, the needle comes to its original position.

⠀

$\large\bf\underline\teal{Conclusion}$

This experiment shows that current carrying wire behaves as magnet.

⠀

$\large\bf\underline\indigo{Precaution}$

Do not touch the end of the wire with your

fingers.
