Answer:
The current is   
 
Explanation:
From the question we are told that  
      The radius of the loop is  
      The  earth's magnetic field is 
       The  number of turns is  
Generally the magnetic field generated by the current in the loop is mathematically represented as 
         
Now for the earth's magnetic field to be canceled out the magnetic field generated by the loop must be equal to the magnetic field out the earth
          
=>     
      Where   is the permeability of free space with value
 is the permeability of free space with value  
        
=>
