Bedwars (stylized as BedWars) is a game developed by Easy.gg based on the fanmade Minecraft minigame of the same name. [160] Similar to the original version, players defend their bed from other opponents while attempting to destroy other player's beds. [161] [162] Unlike the Minecraft version, the game has more weapons to use. [160]

The Earth's magnetic field at 0.5 gauss is too weak to magnetize a lodestone by itself. [9] [10] The leading theory is that lodestones are magnetized by the strong magnetic fields surrounding lightning bolts. [9] [10] [11] This is supported by the observation that they are mostly found near the surface of the Earth, rather than buried at great ...
Paramagnetic materials have a weak induced magnetization in a magnetic field, which disappears when the magnetic field is removed. Ferromagnetic and ferrimagnetic materials have strong magnetization in a magnetic field, and can be magnetized to have magnetization in the absence of an external field, becoming a permanent magnet. Magnetization is ...
It is one of the oxides of iron, and is ferrimagnetic; [6] it is attracted to a magnet and can be magnetized to become a permanent magnet itself. [ 7 ] [ 8 ] With the exception of extremely rare native iron deposits, it is the most magnetic of all the naturally occurring minerals on Earth.
Any change to the current through the magnet must be done very slowly, first because electrically the magnet is a large inductor and an abrupt current change will result in a large voltage spike across the windings, and more importantly because fast changes in current can cause eddy currents and mechanical stresses in the windings that can ...
Worst-case inrush happens when the primary winding is connected at an instant around the zero crossing of the primary voltage (which for a pure inductance would be the current maximum in the AC cycle) and if the polarity of the voltage half-cycle has the same polarity as the remanence in the iron core has (the magnetic remanence was left high ...
A head on a spike (also described as a head on a pike, a head on a stake, or a head on a spear) is a severed head that has been vertically impaled for display. This has been a custom in a number of cultures, typically either as part of a criminal penalty following execution or as a war trophy following a violent conflict.
