A coil of copper wire when connected to a flashlight cell becomes an electromagnet. What will make the magnet stronger?

Two things, either increase the voltage by adding another battery (to increase current in the coil), or increase the number of turns in the coil. We're assuming you wound your coil around some nice ferromagnetic material and are using that for a core.

How can a electromagnet pick up more metal things?
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.
Why capacitor is connected to earth in circuit?
when a capacitor is connected to earth the potential of capacitor becomes zero. as a result all the charge residing on the conductors of a capacitor passes away and the final charge on capacitor becomes zero
If the axolemma becomes more permeable to potassium ion?
a stronger stimulus will be required to cause an action potential
What are black holes and how are they formed?
Black holes are created when in a Supernova-explosion or after a collision between two neutronstars (which are mini black holes). The star collapses and the gravity becomes stronger and stronger, dragging everything towards the center. In the end, the gravity becomes so strong that not even light can escape.
An electromagnet becomes stronger when?
You run more copperwire around the coil, or induce more curent in the wire.

Do amps volts or watts affect electric magnet strength?
An electromagnet becomes stronger when the current through it increases, i.e. the Amps.
Does the size of the core affect the strength of a electromagnet?
That's because the strenght of the electromagnet is related to the number of coils then, the more coils gets more strenght because as you add more coils to the electromagnet you have more and more magnetic field. -I hope this answer helps you if you have a question regarding any questions on any subject please fell free to ask. Thank You

What do scrap heap magnets repel?
The strength of any electromagnet changes when the current (amperes) or the number of 'turns' of wire in its wire coil changes. Increasing either of them makes the magnet stronger.

Why a magnet placed inside a solenoid does not show magnetism?
The solennoid is an electromagnet and only becomes magnetized when the power is applied.
Why copper wire becomes stronger when bent?
It becomes weaker and breaks when bent many times.
