El inducido de un generador eléctrico bipolar consta de una núcleo cilíndrico de 20cm de longitud y 10cm de diámetro, sobre donde va arrollado 200 espiras dispuestas en dos circuitos en paralelo la inducción magnética en el entre hierro es de medio . Calcular la fem media generada cuando el inducido gira 30 revoluciones por segundo

The slotted link is pinned at o, and as a result of rotation it drives the peg p along the horizontal guide. compute the magnitude of the velocity and acceleration of p along the horizontal guide. compute the magnitudes of the velocity and acceleration of p as a function of θ if θ=(3t) rad, where t is measured in seconds.

Part 1: a magnetic levitation or maglev train rides rails without touching them. explain how this works using your data. include the appropriate magnet drawing in your answer. part 2: two objects are near a bar magnet. one is about 1 cm away, while the other is 6 cm away. compare and contrast the magnetic force that affects each object. use your data to answer the question
