Hi all, if i'm in the wrong place please do let me know...I am in first year electrical engineering and I am asked to do a project with a group but we are having trouble selecting which project make from this list: 1. MAGLEV : Use of magnetic field to build a magnetically levitating model train 4. Current meters : Magnetic field is used to detect the current value in conductors and in electronic tracks 5. Digital compass : The Earth’s magnetic field is used to find the direction of the “Magnetic North Pole” 7. Mapping of equipotential surfaces - Mapping and plotting the equipotential surfaces between two conductors at different potential levels 8. Magnetic breaking system : Use of magnetic field to build a magnetic breaking system 9. Ignition coil : Used in cars for spark plugs Can you please help us choose? Now I am thinking of choosing the "Magnetic Breaking System"...do you think its possible to design a simple model of that system? if it is possible, how many students would it take to make it? given that we are required to write a report as well and not just make the thing. We will buy the stuff locally so please put that in consideration as well, we don't want to wander for sophisticated electronics or sensors which we won't find in the local egyptian market.
