This my first updates. So this purpose of this post is to elevate our general knowledge towards nature science and boots knowledge or engineering students. Tesla (symbol T), SI derived unit of magnetic flux density (or magnetic inductivity), named after Nikola Tesla. Down there i've attached a video which a group of several people testing the strongness of 4T magnet. They put in ferromagnetic in it to analyze the attractive force that could be produced but the magnet.
I'm sure very all of u are showered intensely with question 'whattaheck a 4T magnet? how strong is 4T magnet? and all those magnet thingys come to ur mind. Hahaha butthurt!
There's some facts that i could share with y'all ;
31 µT (3.1×10−5 T) - Earth's magnetic field in equator line(garisan khatulistiwa)
5 mT - Strength of magnet where it's used in fridge magnet
1.25 T - Neodymium Strength of magnet where its used in Neodymium magnet
1 T to 2.4 T - Strengthh of magnet in hi-fi speaker
1.5 T to 3 T - Strength of magnet used in hospital for MRI
Enjoy the video hope y'all like my first post - paly ^^
