This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.]]> 2022-02-04 16:49:21 UTC https://padlet.com/mannatmanoj2/539lq8931j8n2pl1/wish/2029773965 mannatmanoj2 https://padlet.com/mannatmanoj2/539lq8931j8n2pl1/wish/2029780762 Magnets can be found in the simplest or most complex devices you use every day. From home appliances such as the refrigerator, microwave oven and electric fan, to your company's office equipment such as computers and printers.]]> 2022-02-04 16:53:20 UTC https://padlet.com/mannatmanoj2/539lq8931j8n2pl1/wish/2029780762 mannatmanoj2 https://padlet.com/mannatmanoj2/539lq8931j8n2pl1/wish/2029786914 When the electrical current flowing through the voice coil changes direction, the coil's polar orientation reverses. This changes the magnetic forces between the voice coil and the permanent magnet, moving the coil and the attached diaphragm back and forth.]]> 2022-02-04 16:57:04 UTC https://padlet.com/mannatmanoj2/539lq8931j8n2pl1/wish/2029786914 mannatmanoj2 https://padlet.com/mannatmanoj2/539lq8931j8n2pl1/wish/2029804091 Magnetic locks use electromagnetism to control the entire locking mechanism. When the magnet is energized, it bonds to the armature and locks the door. ... As the electric power activates the magnet, the bolt locks the door. To unlock the door, simply remove power.]]> 2022-02-04 17:00:00 UTC https://padlet.com/mannatmanoj2/539lq8931j8n2pl1/wish/2029804091 mannatmanoj2 https://padlet.com/mannatmanoj2/539lq8931j8n2pl1/wish/2029817747 The lid of the Perfume bottle simply gets attracted to the perfume's Atomizer, (the top part of a perfume bottle.) It closes the perfume bottle and keeps it intact.]]> 2022-02-04 17:07:41 UTC https://padlet.com/mannatmanoj2/539lq8931j8n2pl1/wish/2029817747 mannatmanoj2 https://padlet.com/mannatmanoj2/539lq8931j8n2pl1/wish/2029835968 The Magnetic Snaps in the lock attract to each other to secure the purse from opening up and is also put for safety reasons. ]]> 2022-02-04 17:18:49 UTC https://padlet.com/mannatmanoj2/539lq8931j8n2pl1/wish/2029835968 mannatmanoj2 https://padlet.com/mannatmanoj2/539lq8931j8n2pl1/wish/2029849662 Roughly 4,000 years ago, a Greek shepherd named Magnes is said to have been tending his sheep in a region of northern Greece called Magnesia. He took a step and suddenly found that the nails that held his shoe together and the metal tip of his staff were stuck fast to the rock he was standing on! Intrigued, he began digging and discovered the first recorded lodestone. Lodestones were henceforth known as “magnetite,” probably named after Magnes or Magnesia.]]> 2022-02-04 17:26:09 UTC https://padlet.com/mannatmanoj2/539lq8931j8n2pl1/wish/2029849662 mannatmanoj2 https://padlet.com/mannatmanoj2/539lq8931j8n2pl1/wish/2031158164 It works like this: A magnetic loop antenna (copper coil) is used to create an oscillating magnetic field, which can create a current in one or more receiver antennas. If the appropriate capacitance is added so that the loops resonate at the same frequency, the amount of induced current in the receivers increases.]]> 2022-02-06 05:58:05 UTC https://padlet.com/mannatmanoj2/539lq8931j8n2pl1/wish/2031158164
