    Undergrad How does a calibrated Hall Probe work?

    :confused: Hm I'm not taking so high level physics yet so I don't really understand. So basically the hall probe is connected to a Gauss meter so direct readings of magnetic field strength can be obtained?

    Undergrad How does a calibrated Hall Probe work?

    I'm supposed to plan an experiment using a calibrated hall probe to investigate the relationship between Magnetic field strength (B) of a coil and the distance (x) from the centre of the coil. I'm supposed to be able to take direct readings from the calibrated hall probe to calculate B, but how...

    Relationship between potential and induced emf?

    Then how is there an induced emf? [PLAIN]http://img207.imageshack.us/img207/5853/93128344.png Do you take "Force" to be in direction of the velocity?

    Solving Ice's Acceleration Down a Sloped Roof

    Force by gravity in direction of slope = 9.81*1.5*sin60 Net force = 9.81*1.5*sin60 - 3.0 Net force = ma a = (Net force)/m

    How to determine direction of forces in free body diagrams?

    For instance, in the below diagram: [PLAIN]http://img101.imageshack.us/img101/3205/59914396.png How do you know if the reaction force on the beam is in Direction A or B? How do you determine the correction direction?
