Where Form 8655 Magnetic 2024

Our topic for today is the 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. Come on, take the far magnet and keep it on a table. Wow, such a colorful spacecraft! Let's go there. Keep a transparent sheet on top of the magnet. Now, take some iron filings and sprinkle them on the paper. Arrange yourselves properly. The iron filings will start arranging in a definite pattern around the magnet. Okay, this pattern is called a magnetic field. The lines along which the iron filings are arranged 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.
