Electromagnets are created using charged and insulated wire wrapped around a piece of iron. uncharged and insulated wire wrapped

Inessa [10]

I think the correct answer would be <span>charged and insulated wire wrapped around a piece of iron. The charge in the wire would make magnetic fields through the aid of the magnetic properties of iron. Hope this helps. Have a nice day.</span>

Can any person help me for this problem? Anyone's welcome

noname [10]

Answer:

The anode made of the impure copper

The cathode made of pure copper

The electrolyte of copper (II) sulfate CuSO₄ solution

The silver impurities at the anode due to their high tendency of accepting electrons and being a stronger reducing agent than either copper or zinc will remain relatively in place and relatively stable and will not actively take part in the oxidation reaction taking place at the anode

The zinc impurities will be the first element of the three metals to give up electrons and go into the solution as zinc ions due to their high tendency to loan out two electrons and become oxidized into Zn²⁺ ions

The drawing of the electrolytic cell created with Microsoft Visio is attached
