Talk About It!
You just learned about microbots that are driven by magnetic forces and can go inside the human eye.
Why else might scientists make a tiny robot? What else could tiny robots do?
Do you have a magnetic idea for the future? Write what you think magnets may be used for in the future.
Some answers are:
they can go into tiny places, like inside the human body;
they can do hidden work;
they can run on less power than big robots;
they can work in tiny teams to explore new places
Now draw a sketch of your magnetic idea.
