You run more copperwire around the coil, or induce more curent in the wire.
Electromagnet perhaps?
The solennoid is an electromagnet and only becomes magnetized when the power is applied.
More than what? - An electromagnet can pick up metal due to its magnetism - assuming it is turned on. If you increase the current, the electromagnet becomes more powerful - but you must be careful not to pass too much current, otherwise the wires might burn through.
An electromagnet becomes stronger when the current through it increases, i.e. the Amps.
