... nickel and cobalt, together with alloys of these metals and aluminium, are the best examples. The majority of small permanent bar magnets used at school are called ALNICO magnets. Can you work out how the name is derived? Ferromagnetic comes from the Latin ferrum, meaning ‘iron’. If any magnet is fr ...

Electromagnets
... conductive wire can also increase the strength of the electromagnet. Changing the wire is one just way to change an electromagnets strength. Another way to change the strength is to change the other part of the electromagnet: the magnetic core. Some magnets are naturally stronger than others, so usi ...

Magnetic forces on moving charges – More than just a
... Because all our charges are moving along at a speed of v m/s they will travel v metre every 1 second. In every metre of current there are n charges, so our little observer , counting the charges going by, will see nv charges go past every second. This means a total charge of Q = nvq passes each se ...

Electromagnetism - Delta Education
... In this Delta Science Module, students are introduced to electromagnetism and the conversion of energy from one form into another by means of electric currents and magnetic fields. ACTIVITY 1 Students review the properties of magnetism by observing the interaction of magnets with ferrous and nonferr ...
