Some materials are magnetic and others are not. How can we determine an object is magnetic experimentally?
the compass would work, another way would be to simply expose the material to a posive magnetic field, then a negative magnetic field. If the mateial is magnetic, it will respond to one or the other field. A visual response would indicate magnetism.
Use a compass. When a compass is placed overtop of a magnet or a magnetic object, it points either north or south, telling whether or not the pole is a north or a south pole (positive or negative).
That's an obvious one ! Simply pour 13 gallons of chocolate pudding over object to be tested and then bark. If the object is magnetic it will be, unless of course it isn't.
