BBC Bitesize, [1] also abbreviated to Bitesize, is the BBC's free online study support resource for school-age pupils in the United Kingdom. It is designed to aid pupils in both schoolwork and, for older pupils, exams .
In mathematics and physics, the right-hand rule is a convention and a mnemonic, utilized to define the orientation of axes in three-dimensional space and to determine the direction of the cross product of two vectors, as well as to establish the direction of the force on a current-carrying conductor in a magnetic field.
Magnets exert forces and torques on each other through the interaction of their magnetic fields.The forces of attraction and repulsion are a result of these interactions. The magnetic field of each magnet is due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons) that make up the mater
Megamaths is a BBC educational television series for primary schools that was originally aired on BBC Two from 16 September 1996 to 4 February 2002. For its first three series, it was set in a castle on top of Table Mountain, populated by the four card suits (Kings, Queens and Jacks/Jackies, and a Joker who looked after children that visited the castle and took part in mathematical challenges).
The dimension of magnets varies between different versions, while typically in the range of 1.4 [29]-2 [28] mm square shape with a lower height. The poles of magnets were positioned as a checkerboard array to fit the magnetic field generated by the PCB platform. The robot can be built in different size depending on the size of the array.
[2] [3] A book on the BBC Micro noted that L integrated math concepts into the characters and story instead of just simply displaying sums. [4] A UK teaching guide in 2010 said that L was an "old, excellent example of a well-thought-out, text-based mathematical game" that was "is worth buying a copy for yourself."
The magnetic field of larger magnets can be obtained by modeling them as a collection of a large number of small magnets called dipoles each having their own m. The magnetic field produced by the magnet then is the net magnetic field of these dipoles; any net force on the magnet is a result of adding up the forces on the individual dipoles.
The world's first power plants entered service in 1883, and by the following year, people realized the possibility of using electricity to power a variety of household appliances. Inventors and engineers soon raced to develop such items, starting with affordable and durable incandescent light bulbs, perhaps the most important of the early ...
