    ABS System sensor magnet
    An anti-lock braking system or anti-skid braking system(ABS) is an automobile safety system that allows the wheels on amotor vehicle to maintain tractive contact with the road surface according to driver inputs while braking, preventing the wheels from locking up (ceasing rotation) and avoiding uncontrolled skidding. It is an automated system that uses the principles ofthreshold braking and cadence braking which were practiced by skillful drivers with previous generation braking systems. It does this at a much faster rate and with better control than a driver could manage.
    There are four main components of ABS: wheel speed sensors, valves, a pump, and a controller.

    Wheel Speed Sensor Magnet
    A speed sensor is used to determine the acceleration or deceleration of the wheel. These sensors use a magnet and a Hall effect sensor, or a toothed wheel and an electromagnetic coil to generate a signal. The rotation of the wheel or differential induces a magnetic field around the sensor. The fluctuations of this magnetic field generate a voltage in the sensor. Since the voltage induced in the sensor is a result of the rotating wheel, this sensor can become inaccurate at slow speeds. The slower rotation of the wheel can cause inaccurate fluctuations in the magnetic field and thus cause inaccurate readings to the controller. sensor alnico rod magnet

    Alnico Magnet Manufacturing Methods
    Most alnico magnets are manufactured using typical foundry casting techniques, where the molten alloy is poured into sand molds. Very small magnets, usually one ounce or less, are produced using press and sinter techniques. Sintered Alnico magnets have features which make them particularly effective in very small precision devices. Sintering magnets with small holes and intricate shapes is possible. Sintered magnets are available in both isotropic and anisotropic form, with a broad range of unit properties. Their magnetic properties are similar but often slightly lower than cast magnets of equivalent grade.

    Alnico magnets, cast and sintered, are finished ground using abrasive grinding to produce the final shape and tolerance. Once ground the material is a shiny metallic finish. These materials are brittle and cannot be machined or drilled.
