Iron man wears an awesome ironsuit. He is flying over high current carrying wire. Will he be affected?

yes

Explanation:

when when a current-carrying wire creates a magnetic field.

Ferromagnetic metals such as "iron" or Nickel would be attracted

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .
