Just watch. Contact corrosion, weakening of the connection, whatever the cause, it will happen. There's a reason mechanical connectors have been used for this long, they work, and they are simple. Plus each time you plug and unplug the connection you clean the contact.

Or are they inductive connectors, having no contacts at all?

That would be nice, but no. Just look at the animated picture in Apple's page, right where it talks about MagSafe. Clearly there are conductive (metallic) pins. I had heard that inductive connectors have significant losses and so they are not suited for high-power tasks; but apparently it is not so for electric car chargers.Contrary to what h2 said in grandparent, the MagSafe connector is not so different from a regular connector; but it is guided and held in place by magnetic forces, so it does not need to be 1 cm long. Looks good.
