Math Blaster for 1st Grade is a 1999 educational video game in a line of educational products originally created by Davidson & Associates and continued by Knowledge Adventure. The game was re-released in 2000 as Math Blaster Mission 2 .
The word magnet comes from the Greek term μαγνῆτις λίθος magnētis lithos, [4] "the Magnesian stone, lodestone". [5] In ancient Greece, Aristotle attributed the first of what could be called a scientific discussion of magnetism to the philosopher Thales of Miletus, who lived from about 625 BC to about 545 BC. [6]
The second of Maxwell's equations is known as Gauss's law for magnetism and, similarly to the first Gauss's law, it describes flux, but instead of electric flux, it describes magnetic flux. According to Gauss's law for magnetism, the flow of magnetic field through a closed surface is always zero.
Magnet was a children's programming block aimed to preteens that aired on HBO Family. It first aired on August 26, 2001 alongside Jam , a block made for preschoolers. [ 1 ] Until 2004, the block aired on afternoons and evenings at 5pm to 7pm every day.
(BH) max can be graphically defined as the area of the largest rectangle that can drawn in the second quadrant of the B-H loop.. The maximum energy product is defined based on the magnetic hysteresis saturation loop (B-H curve), in the demagnetizing portion where the B and H fields are in opposition.
One of the first was the oscillating electric wire invented by James Marsh in 1824. [6] [5] This consisted of a wire pendulum dipping into a mercury trough, suspended between the poles of an electromagnet. When current was passed through the wire, the force of the magnet made the wire swing sideways, out of the mercury, which broke the current ...
