Wembley (1923 & 2007), London, England. The original Wembley, built in 1923 famed for its iconic twin towers, and for being home to the English National team, hosting FA Cup Finals and The 1966 World Cup. Replaced in 2007 with a new stadium, sporting a similarly iconic 134 metre Wembley Arch.
A magnetic field can be formed by passing electric current through a wire, and electromagnets work on this basic principal. Electromagnets are used for creating plenty of appliances ranging from motors, speakers, heads for tape drives, and hard disks; here's a brief insight to electromagnets.
'What effects the strength of an electromagnet?' Introduction: An electric current flowing through a wire produces a magnetic field. Coiling the wire produces a stronger magnetic field. Coiling it around a soft iron core increases the strength effect; raising the current or the number of coils increases it further.I am going to investigate the raising of the current and how it affects an electromagnet.I think the electromagnet will produce a stronger magnetic filed and pick up more iron fillings. Aim: To investigate factors which affect the strength of the electromagnet and make the strongest electromagnet possible. am going to investigate the raising of the current and how it affects an electromagnet.
