Fysica formularium:

Hoofdstuk 7 magnetisch veld, veldvector, veldlijnen

Grootheid: B (magnetische veldsterkte)

Eenheid: T (tesla)

Formule magnetische veldsterkte bij een stroomvoerende geleider:

/B/ = µ (mu) / 2pi * I (stroom door geleider) / r (afstand tot geleider)

Permeabiliteit van de middenstof (afhankelijk van de stof): vacuum µ° = 1,257 * 10^-6

Formule magnetische veldsterkte bij een stroomvoerende spoel:

/B/ = µ * I * N (aantal windingen / rondjes) / L (lengte van de geleider / draad)

Windingsdichtheid: N/L (kleine l)

= van je weg

= naar je toe



Hoofdstuk 8 kracht op een elektrische stroom in een magnetisch veld

Lorenzkracht op een stroomvoerende geleider:

Lorenzkracht = een doorstroomde geleider ondervindt een kracht.

Kracht = F (Newton / N)

Magnetisch veld / inductie = B (Tesla / T)

Stroom = I (Ampère / A)

Kleine l = lengte geleider (meter / m)



Kracht tussen twee evenwijdige stroomvoerende geleiders:
