  • Our topic for today is Magnetic Field.

  • You are late again.

  • Hurry up.

  • Something is wrong.

  • The region surrounding a magnet in which the force of the magnet can be experienced is called its magnetic field.

  • Seems like a nice spot to relax.

  • It's an alien ship.

  • We must be careful.

  • Run.

  • Take a bar magnet and keep it on a table.

  • Wow. Such a colorful spacecraft.

  • Let's go there.

  • Activating transparent shield.

  • Keep a transparent sheet on top of the magnet.

  • Now, take some iron filings

  • and sprinkle them on the paper.

  • Arrange yourselves properly.

  • In reality, the iron filings will arrange immediately after getting sprinkled.

  • The iron filings will start arranging in a definite pattern around the magnet.

  • This pattern is called a magnetic field.

  • The lines along which the iron filings arrange are called magnetic field lines.

  • The magnetic field lines show the direction and strength of the magnetic field.

  • Magnetic field lines always start from the north pole of the magnet and end at the south pole.

  • Inside the magnet, their direction is from the south pole to the north pole.

  • Thus, the field lines form closed loops.

  • Field lines never cross or intersect each other.

  • The closeness of the magnetic field lines tells us about the strength of the magnetic field in that area.

  • The more closely packed lines indicate a stronger magnetic field.

  • Therefore, we can see more iron filings sticking at the poles.

  • As the lines spread out, the magnetic field weakens.

  • Why did I come here?

  • That was the best time of my life.

  • You had an amazing experience.

  • Yes. I miss my friends.

Our topic for today is Magnetic Field.
