If I wound two coils on the same core and the direction of winding is the
same for the two coils(say,clockwise), and connect an a.c voltage source two
one of the coils (name it primary). What will be the phase of the induced
voltage on the other coil (the secondary)? Will be in-phase with the primary
voltage or out-of-phase with it?
Thanx for help

The simplest way of finding this out is to experiment with some lengths of
insulated wire and a piece of iron or steel to wind the wire on (a large
bolt).

Put a voltmeter on the secondary winding and use a battery with a switch to
power the primary winding.
