Magnetic Fields experiment
MAGNETIC FIELD
Magnets offer an introduction to attraction and repulsion, and to act at a distance (magnetic field) and we will see the Magnetic Fields experiment below.
OBJECTIVE
The objective of the Magnetic Fields experiment is to investigate whether one magnet will expertise and exert each attractive and repulsive force with alternative magnets or not. And as we know magnetic fields are invisible, but with this activity, we can see the appearance of magnetic field lines.
APPARATUS
● Magnets, different types (at least 2pairs)
● Nails
● Iron filings in a pepperpot
● Compasses
● Other materials for testing magnetic behavior
● Small scraps of paper
● Sheets of papers
● A pen or pencil
Magnetic Fields experiment PROCEDURE
Whether one magnet will expertise and exert each attractive and repulsive force with alternative magnets or not.
● Hold pairs of magnets and feel the forces between them, repulsions in addition as attractions.
● Use the magnets to undertake to draw in nails and alternative materials. a number of them (such as little scraps of paper) cannot be attracted by a magnet.
● Place a magnet beneath a bit of paper and scatter iron filings on prime to reveal a magnetic field pattern. The aim of the sheet of paper is to stop direct contact between magnets and filings since they will be laborious to separate. faucet the paper gently to make sure the filings don’t stick together.
● Place compass needles tip-to-tail close to a magnet.
● Record their directions, to plot the magnetic field as constant fieldlines.
● Suspend a magnet and show it aligns roughly North and South. The pole that points North is the “North-seeking pole” of the magnet.
We know magnetic fields are invisible, but with this activity, we can see the appearance of magnetic field lines.
● Place the bar magnet in the middle of the paper. Trace the outline of the magnet – that way you can put it back in the exact same spot if it gets bumped.
● Place the compass at one pole of the magnet and make a dot next to it showing the direction the compass arrow points.
● Move the compass so that the base of the arrow is at the dot you’ve just made. Now make a new mark where the tip of the arrow is pointing this time.
● Keepdoingthisuntilyoureachtheotherendofthemagnet.
● Connect the dots. You’ve just drawn one magnetic field line!
● Go back and begin again, starting at a different spot than you did the first time. Repeat the above steps.
● Repeat the process until you have drawn as many lines as you can for both ends of the magnet. You will now have an accurate representation of magnetic field lines.
● Different magnets will give you different field lines. Try repeating these steps with magnets of different sizes and shapes.
● You can also “draw” field lines with iron filings, available at most hardware stores. Use the same magnet and paper (with your drawn field lines) from the above activity. Put the magnet back in place under the paper, then sprinkle the filings on top. Tap the paper gently.
OBSERVATION
In the above Magnetic Fields experiment, we observed that one magnet will experience and exert each attractive and repulsive force with different magnets.
It permits the introduction of the thought that magnets have 2 completely different ends or faces, known as poles.
And we can observe that filings fall into place along the very same lines you drew.
CONCLUSION
The Magnetic Fields experiment thus proves that magnets have 2 completely different ends or faces, known as poles and they create magnetic fields. As we know that we can see the magnetic field lines are invisible, but with this activity, we have seen the appearance of magnetic field lines.
