Preliminary Designs
Bullyard State School
Mr. Brennan's 6/7th Grade
By Todd
This is the design of the year 6/7 class of Bullyard
State School that they think is workable. There are four negative magnets
stuck on to the wooden frame and another four negative magnets stuck
to the ball. With the negative magnets parallel to each other it should
push it but with another one opposite it, it should push it back.
Response from Expert Dan Andrews:
This is interesting in that it is attempting
to almost float the ball by using magnetic repulsion. It is possible this
could work, but how to you allow the ball to move when pushed? For example,
if I pushed on the ball in one direction, wouldn't the magnets on the
other side try to push the ball back?
How do you allow the ball to be pushed, and
have it keep moving?
What about up and down as well?
